2018 Subaru WRX and WRX STI Pair Updated Looks With Performance Upgrades

For 2018, Subaru has given the WRX and WRX STI a mild refresh on the outside, and a few significant tweaks under the skin. Starting with the exterior, the lower grille openings on both models have been enlarged and given a bit of extra black trim for a more aggressive look. In fact, the change is a bit reminiscent of the dearly departed Mitsubishi Evo, with the black trim of the lower center grille extending to the bottom of the bumper. The WRX Limited and all STI models also get turning LED headlights, and the STI gets bigger 19-inch wheels.


The interior also features subtle tweaks including a larger screen in the instrument panel for all models, as well as thicker door glass and foam in the windshield header to the make the car quieter. Both models also now come with roof rack mounting brackets, a new rear armrest with cupholders, and, according to Subaru, improved interior materials. And the WRX and STI are also now available with eight-way power adjustable Recaro seats. The Recaros are standard on the top trim STI, optional on the standard STI, and available in the new Performance Package for WRX models.


This brings us to perhaps the biggest update, that aforementioned WRX Performance Package. In addition to the Recaro seats, it comes with upgraded brake pads covered in bright red calipers. The package also eliminates the moonroof, which hardcore enthusiasts know will save weight up high.


The STI gets a notable brake upgrade. New Brembo brakes feature six-piston calipers at the front, and two-piston units at the back, and they’re all painted a vivid yellow hue. Those calipers act on bigger, drilled rotors using equally enlarged brake pads. Subaru also retuned the car’s Driver Controlled Center Differential (DCCD). Both the WRX and STI also have retuned suspension all around.


If this all sounds great to you, you should be able to pick one up at your local Subaru dealer this spring.

8 Reasons Why This Subaru is The Best Performance Car Just About Anyone Can Afford

For the 14 years that the Subaru WRX has been on sale in the US, it’s succeeded as an affordable, beginner, sporty, confidence inspiring, do-everything enthusiast car. It’s also used that time to grow up a little bit.

The WRX is no longer just a car for boy-racers and rally junkies. With a starting suggested retail price of $26,595, it’s an amazing performance car at a great value.

Here are a few reasons this car is such a steal:

It handles incredibly well.

Like many other all-wheel drive cars, WRXs have always been plagued with not-so great handling. But in the current generation WRX, you’re rarely reminded of that dim past.

Thanks to a very clutch torque vectoring system that Subaru has implemented in this new generation of WRX, the car corners, very, very well. Its stiffer chassis, reworked sport suspension, and well-designed Dunlop summer performance tires also play major roles in this.

It has top-notch safety features.

Putting aside the WRX’s active safety and handling features that’ll keep you out of harm’s way, the cabin of the WRX is also an
incredibly safe place to be if you are in an accident.

After receiving top ratings in six different safety tests given by the Insurance Institute for Highway Safety, the WRX scored an IIHS Top Safety Pick award for 2015. Models equipped with Subaru’s accident avoidance EyeSight technology were awarded with the even higher, IIHS Top Safety Pick+ award.

It’s got tech!

All WRXs now come standard with Subaru’s Starlink entertainment system. Starlink uses an easy to navigate touchscreen system and is designed to pair with your iPhone or Android device to help play music through the car’s sound system without issue.

When spec’d with the EyeSight safety system, the WRX can alert the driver if he or she is drifting out of a lane. If the car senses an impending frontal collision, it can automatically apply the brakes. You don’t see the Mazda Miata or the Ford Focus RS with that kind of tech!

It has a great motor.

As it comes from the factory, the WRX uses a strong motor that allows for great performance and optimal fuel economy. 0-60 in about 5 seconds and an average fuel mileage rating of 25 MPGs was once unheard of in these cars. Now it’s the standard.

There’s tons of space.

With 37.1 inches of headroom in the backseat of the WRX, it’s a reasonably comfortable place to be. Even for taller people.

If you’re looking for more of a cargo hauler than a people mover, the rear seats also fold down to extend the cargo room in the event that the trunk’s primary 12 cubic feet of storage isn’t enough. Though for most tasks, it’s pretty much perfect.

It can be decked out with insane custom modifications. (If you’re into that sort of thing.)

Though the WRX might appear a little more family friendly and mature at first glance, if you’re into tuning or aftermarket modifications, there’s still a whole world of parts and a very welcoming enthusiast community to explore.

You’re basically driving a race car.

Since their early days in the World Rally Championship and continued through today with their involvement in Rally America, Subaru has been able to grow an impressive fan base of motorsport junkies.

For these rally fans, the top choice for a daily driver is almost always the WRX. Or if not the WRX, then its slightly more track-ready sibling the WRX STI. There’s nothing like going to a racing event in the middle of nowhere and seeing a car that resembles your own car being professionally driven in ways that are almost beyond comprehension.

It comes with friends.

Owning a WRX is like joining a secret club. When passing another WRX on the road, it’s customary to wave. From experience, I can tell you that you may get a slight tingling sensation inside each time this happens. Trust me, it’s normal. And it never gets old.

Subaru WRX STI Modification Guide

The Subaru WRX STi is a fantastic package with solid Brembo brakes, a high-performance suspension, and around 300 turbocharged horsepower being put to the ground with pure all-wheel-drive traction. It is a deadly back road weapon as-is, but there is a lot of room for improvement should you want to take your rally car the the next level.

While better tires will improve any car, overall, the STi is already very well set up for handling and braking. To raise the excitement level, you can just dive right into adding horsepower.

This post is meant to be a generic, easy to understand guide for anyone who is looking into modifying a Subaru STi. We hope this will help save people the hassle of having to dig through online forums just to find the basic information. Look for more modification guides for other types of cars in the future.

Stock STi Info:

Engine HP: 300bhp

Wheel HP: 240-250awhp

Boost: 14.5 PSI

The Easy Stuff

Stock Subaru WRX STI Engine Bay

Stage 1:

This is a reflash of the car’s ECU that will raise the boost pressure a little to give you more horsepower and torque without any physical modifications to the car. For newer Subarus, this is a good way to make your car a little quicker without voiding the warranty.

Cost: $400-800

Engine HP: ~320bhp

Wheel HP: 250-260awhp

Boost: ~16 PSI

Stock Downpipe (left) vs Aftermarket Downpipe (right)

Stage 2:

The next step is to replace the restrictive stock exhaust with a larger 3-4” exhaust from the turbo to the rear bumper (Turboback Exhaust). You can also add short-ram/cold-air intake at this point. You will need further tuning or an ECU reflash to realize the gains from these modifications, and many kits are sold with hardware and software included.

Stage 2 really helps the engine breathe a lot better. In addition to the car being noticeably louder, you will notice that power no longer seems to fall off after 80mph. Because of the increase in top-end performance, I’d recommend that every Subaru owner modify their car at least to this point. It will be significantly faster than stock, while offering you great value for money spent.

Cost: ~$2000 new, but a lot can be saved if you buy used exhaust parts.

Engine HP: ~350bhp

Wheel HP: 270-280awhp

Boost: ~18 PSI

Stage 2 Plus:

Many people often throw in a few extra modifications to their cars when going stage 2 that can allow for even more power without compromising driveability or reliability. These modifications include larger fuel injectors, a better fuel pump, a front-mount intercooler, equal-length headers, a boost controller, and an external waste gate.

Cost: as much as $3,500 on top of stage 2, but you don’t have to do all of it at once or buy everything brand new.

Engine HP: 350-400bhp

Wheel HP: 290-330awhp

Boost: 18-24 PSI (22 PSI is the reliable limit for the stock turbo, though)

*Note. You should start thinking about getting a stonger clutch here.

Stage 2 Plus is sort of the end of where things are simple and cost-effective for Subaru WRX STis. At this point, you are pretty much maxing-out the stock turbo, and things are about to get much more complicated.

Many folks, including myself, tend to stop here because ~300awhp is a really nice place in an STi. Your car will blow the doors off of any stock, or lightly modded, STis and Evos, but it will also stay reliable. It’s plenty fast, especially on winding back roads — 0-60 in around 4 seconds flat, 1/4 mile in the high 12s, and it’ll touch 160mph easy.

It’s really all about cost-benefit analysis from here. Do you really need 400 or 500+awhp? Sure it’s a hell of a lot of fun, like having your own private aircraft carrier launch, but there are drawbacks.

The obvious reliability issue is definitely something to think about, but also consider how it will effect the car’s driveability. If you’re like me, and love ripping rally-style back roads, then adding that much power will probably ruin the experience for you. Conversely, if you just wanna be able to run with motorcycles during open highway pulls, then maybe 500awhp is for you. Just consider everything, because you will have to spend a lot of money to go further.

The Harder Stuff

Bigger Turbo Time:

The stock turbo maxes out around 350awhp, and is losing top-end boost well before that. If you want a strong 330awhp or more from an STi, you need a bigger turbo.

But here’s the problem: The stock Pistons tend to fail around 400awhp, or even before if you don’t watch out for knock. Consequently, making big numbers with an STi becomes quite an expensive proposition… to the point where it may be smarter just to buy a different type of car that is more apt to handle “big power” from the get-go.

How much horsepower you make depends on the size of the turbocharger you go with. However, the more power you want, the more parts of the car will need to be replacement parts you’ll need to strengthen the engine and drivetrain.

In terms of cost, I’ve been quoted roughly $12,000 for a built motor and bigger turbo setup that would be good for a “reliable” 450awhp. Sure, if you do everything yourself, it can be quite a lot cheaper, but it’ll cost you your time. I, however, really only wanted around 380awhp from a 20G turbo setup, and $12,000 just wasn’t worth an extra 70awhp or so.

It can get much worse, though. Once you start ordering entire new engines with all forged parts, the total cost can get as absurd as $60,000-$70,000 and beyond. Some people are crazy, and happen to have that sort of money just laying around, I guess. For that kind of money, the sky is the limit on horsepower, and you’re basically at the level of building a full-on race car. Anything “can” be done with an STi, like any car, but for what price?

Alcohol Injection:

Many people use different types of alcohol, commonly methanol, to allow them to push the STi’s boundaries a little further. Basically, alcohol burns a little cooler, thus reducing the risk of knock for cars running around 400awhp on a stock engine. It’s not a bad way to go if you’re really trying to cheat that expensive engine rebuild, but it adds more complexity to the car (ie, it’s just something else to go wrong and have to deal with).

Suspension and Brakes

As stated in the beginning, the STi comes from the factory with incredibly good brakes and a solid suspension. Modifications to the brakes or suspension really depend entirely on what you do with your car.

My own car, at Stage 2 Plus level, is still on the stock suspension but with thicker sway bars front and rear that are set up to reduce understeer a bit. I use my car on real roads, many of which are rally-stage-like back roads with varying road surfaces. Because of the unpredictable nature of the roads I drive on, I need the suspension travel of the stock suspension to keep the car well-composed when things get iffy at speed.

Now, if I auto crossed my STi or took it to track days on a road course, then a lower, stiffer suspension might benefit me. Conversely, if I did rally cross, then I might want to raise the suspension. It all depends on what you feel will benefit your chosen activities with your car.

As for the brakes, like the suspension, the stock Brembos work pretty well even for a car with modifications like mine. I do have slightly better brake pads, but otherwise my brakes are totally stock. Now, obviously, if you are going to take the STi’s performance to an entirely different level, then you should upgrade the brakes accordingly.

Conclusion

Subaru WRX STis are very solid cars up until a certian point (~350whp). Their sweet spot is right around ~300awhp, where performance is quite thrilling, but reliability is still preserved. It is also pretty cheap and easy to get an STi to the 300awhp level, so it’s accessible for most owners. Doing the basic modifications brings out the Subaru’s full raw character, and is really worthwhile for any owner to do.

More can definitely be gotten from an STi, if you have the wallet, the skills, and the patience to deal with the issues that come up at higher horsepower levels. However, for most people, there are far more cost-effective options out there if a 400whp+ is desired.

So when it comes to modifications, a Subaru STi is a great value until it’s not, and there isn’t much too much middle ground in between.

Five Steps to Making More Power in Your Subaru WRX

More Mods For Our Project WRX

The Subaru Impreza WRX is a performance bargain: A quarter-mile time of 13.5 seconds at 101 mph is as quick as any WRX STI we’ve tested, and the standard WRX model is about 10 grand cheaper. Being power hungry, we have investigated a number of claims that even more output—over the stock 265 horsepower and 244 pound-feet of torque—is available with a few simple modifications. As we found, your results may vary. Here’s how we got that extra power:

 _______________________________________________________________________________
STEP 1:The Intake Trick 

Getting more air into the engine’s combustion chambers produces more power, right? Right. After a simple installation, the low-restriction conical air filter and straight intake tube of the K&N Typhoon kit gave us a 17-hp increase at the wheels and a new jolt of torque worth 21 pound-feet. The intake carries its own million-mile warranty and doesn’t void the factory warranty. The downside: It doesn’t meet California emissions regs, and the increased intake noise was hated by the old folks in our office.

__________________________________________________________________________________

STEP 2: The Exhaust Tactic 

We were feeling pretty smart after installing a Magnaflow exhaust. All it took was a few bolts and clamps, and the WRX was putting out a pleasant burble at idle without being too loud. Power was unchanged, but torque increased by 10 pound-feet. Like the intake, the stainless-steel exhaust is guaranteed for life and won’t void the Subaru warranty.

__________________________________________________________________________________

STEP 3: But They Don’t Add Up

We put our project car on a dynamometer with the K&N Typhoon intake and the Magnaflow exhaust (the numbers mentioned earlier were achieved with each performance piece installed solo on the WRX). With both installed, horsepower was up by 11 over stock and torque was up 20 pound-feet—increases that are less than those produced by the modified intake alone. The extra airflow on both ends was apparently too much for the factory ECU to cope with, and it compensated by cutting power right when the turbo reached maximum boost. Either the intake or exhaust works fine alone, but ECU modifications are required to get them to work in tandem.

__________________________________________________________________________________

STEP 4: Let’s Get Serious

So, to get even more power, we had the engine reprogrammed. Remember, that voids your powertrain warranty. We called Cobb Tuning for its AccessPort, which can completely revise the engine software. And to further free up the exhaust, we threw in a Cobb downpipe with a high-flow catalytic converter. The AccessPort connects to the OBD II plug and automatically saves the factory engine programming. It also has preset engine maps for various states of tune, but none that accounts for an aftermarket intake. Cobb says there are too many variables to have a single program, so we got a $460 custom engine tune. After that, wheel horsepower was up 57 to 266, torque increased a staggering 68 pound-feet to 293, and now the engine sounds meaner than Sasquatch’s wife.

__________________________________________________________________________________

BONUS STEP: Getting a Grip

We installed a set of higher-performance Bridgestone Potenza RE-11 tires, swapping out the stock Dunlop SP Sport 01s. Skidpad grip increased from 0.84 g to 0.87 g, with a noticeable reduction in the understeer that plagues the stock WRX.

__________________________________________________________________________________

On The Dyno: Stock vs. Tuned

 
The dyno tests, done at Speed Industry in Troy, Michigan  report horsepower and torque measured at the wheels. Correcting for driveline losses, a conservative estimate is that crank horsepower has been increased by 65, over the stock figure of 265, for a total of 330. The power boost shows up most noticeably at higher speeds. Our souped-up WRX was 0.3 second quicker to 60, at 4.4 seconds, and 0.4 second swifter through the quarter-mile, at 13.1. But the advantage at 100 mph is 1.3 seconds, and the gap gets wider all the way to the 142-mph top speed. So for less than $4000, high-speed acceleration has improved enough to shame any stock WRX STI.

11 Common Illegal Car Modifications

Most vehicles are a compromise designed to appeal to the widest variety of auto buyers. It’s no wonder then that factory stock trucks aren’t brilliant off-roaders and cars have sometimes huge fender gaps. Owners perform modifications to get the vehicle more in line with their ideal vehicle, but sometimes the mods are beyond what the law allows. Here are the ten most common illegal modifications.

Radar Detectors

Most states only prohibit use of radar detectors by commercial vehicles. This means every single trucker you’ve ever seen is running illegally, as they most likely have a quality radar detector in the cab. Other states have odd laws that allow radar detectors, but do not allow you to mount it in the windshield area, as it might obstruct your view of the road. So, it’s legal, but you could still get a ticket. Much like Oklahoma for example, where radar detectors are allowed, but use of one is a traffic violation. Go figure.

Loud Exhaust


Your sweet ‘70s muscle car with the naked lady mud flaps doesn’t need those cherry bombs, and it certainly doesn’t need to be that absurdly loud. An exhaust system can flow extremely well without creating a ton of noise, annoying your neighbors, or attracting local law enforcement. Most cities have a vaguely worded ban on increasing the noise level, and while the cop has no way to prove it’s louder than stock, you’re still getting a ticket. So it’s important to know your local regulations on this. In Kansas for example, state law requires a muffler to be less than 90 decibels when measured from a distance of 50 feet.

Bro Trucks

Trucks have a higher ground clearance than cars, as they are meant to be used for work, and can even see light off-road duty. Some enthusiasts take it a whole lot further and install lift kits. A 4 inch lift usually looks pretty good and offers a nice increase in ground clearance. The monster trucks that are 2 or 3 feet higher than stock tend to handle like a refrigerator on ice skates and can be a danger to the driver and other motorists. Lift laws vary state by state, with some having maximum limits on bumper/light/reflector height. A few states have no limits, but if you’re sitting eye to eye with the dude in the Kenworth, it’s probably illegal.

Lowriders


Like lifted trucks, low riders are subjected to various state laws regarding vehicle height. However, due to a history unfairly tied to gang activity, low riders get more attention from police than even Bigfoot or Grave Digger. If a car is too low, and scrapes, it can be deemed an unsafe vehicle, and ticketed or even impounded. Fortunately, hydraulics were invented as a means around these laws, but most cities prohibit the use of hydraulics while moving, others ban them above 15 mph.

Under Body Neons

Laws prohibiting additional lighting on your ride are meant to prevent losers that would pretend to be police. If you read the specific laws, they usually ban flashing or rotating blue and red lighting, and spotlights. Some areas have vague laws, and the local city revenue generation squads do their best to find anything to cite. Underbody neon kits were popular at the turn of the century, but recently the trend has faded. While driving with them on can look pretty cool if done right, it’s a sure way to get an expensive ticket.

Emissions Removed

Back in the ‘70s, you could remove the emissions equipment from a smog choked car, do a little carb tuning, and it wasn’t unbelievable to see a gain of 30 or 40 horsepower. 40+ years later, it’s not the ‘70s anymore. Modern fuel injection combined with dozens of computers and sometimes hundreds of sensors make for an engine that can be powerful and meet emissions standards (yes even California). All of the Big Three have recently built supercars with a minimum of 650 horsepower, while meeting EPA regs. Stop unbolting stuff you need.

Headlights/Taillights Modified

Altezza tail lights were one of the first noticeably visible tuner mods, debuting on the 1998 Lexus IS, and shortly thereafter, every single Honda Civic in the high school parking lot. The clear and chrome housings looked startlingly different, but early models didn’t bother looking into DoT certification. The same thing happened with headlights, with varying levels of chrome, black paint, or fake carbon fiber. The dollar store build quality led to many of them leaking or fogging, and a strict safety inspector will call you out on them.

Super Dark Tint

This one is confusing, as tint laws vary from state to state. It’s not just the tint percentage (a measurement of how much light can filter through the tint), but what windows can be covered. Unfortunately, it seems to be selectively enforced, as a 5% limo tint is ignored by LEOs in some areas, but get a fix-it ticket in the town next door. Best bet is to just ask a reputable tint shop about the local laws. Some shops won’t even install illegal tint.

Plate Frames

Seriously. Who would have thought that those cheesy bling plate covers would be illegal? Unfortunately, all the plastic crap sold in auto parts stores isn’t illegal, so someone is still going to dress up their ’87 Ford Festiva. Before they do, let them know that any plate frame that covers any part of the numbers, letters, or state name is illegal and can receive a ticket.

Nitrous

Okay, sure, there’s not a single nitrous manufacturer on Earth that claims it’s legal to have a bottle hooked up for use on the street. Still, probably 95% of the time a street car receives a nitrous injection kit, it isn’t used just on the track. Sometimes it doesn’t ever see the track. The reason for its illegality is the unknown danger first responders would face in an accident. That high pressure nitrous bottle in the back of your Pinto that just puked its gas tank onto the highway, well, that’s a dangerous situation, and anything that makes firemen nervous should be banned on the street.

Rolling Coal

If you want to spend a lot of money to burn more fuel without the side effect of horsepower, buy a Harley. If you want to spend a bit less, but up the dumb factor, then rolling coal is your thing. Yes, people spent time and money altering their diesel trucks to burn far more fuel than necessary, just to make smoke pour out the exhaust like a 100 year old train. Oh, there’s also the extra wear it causes, leading to a shorter engine life, and the loss of power. Yes, they pay extra to waste more fuel and go slower. New Jersey, Illinois, and Texas, among others, are working on legislation to make this a serious fine, in some cases as much as $5,000.
