2015-2021 Subaru WRX STI Aftermarket Parts

2015-2021 Subaru WRX STI Aftermarket & Performance Parts

The 2015-2021 Subaru WRX STI is a fantastic platform for aftermarket parts and modifications. Whether you're on a mission to squeeze more horsepower out of your Subaru WRX STI or just want to change the aesthetics, the aftermarket world is bursting at the seams with possibilities.

However, finding the perfect 2015-2021 Subaru WRX STI aftermarket parts to match your goals and budget can be tricky. You want your parts to fit properly and not sacrifice reliability. Figuring out performance parts, JDM-style upgrades, and OEM replacements can feel overwhelming.

Picking the Right 2015-2021 Subaru WRX STI Aftermarket Parts

The sheer volume of options for Subaru WRX aftermarket parts is huge. This can be exciting and overwhelming. So, where do you even begin with 2015-2021 Subaru WRX STI aftermarket parts? That depends on your goal, but some good places to start exist no matter your goal.

Intakes and Exhausts: Breathe Easy, Boost Power

Want to hear your boxer rumble a little louder and give it a little more kick? Aftermarket intakes and exhausts are great starting points for your modding journey. We put a Cobb Tuning cat-back exhaust system on my 2017 STI, and hearing that boxer growl is something else.

Aside from the amazing sound, we immediately saw improved throttle response. Upgrading to a less restrictive cold-air intake is another great mod.

Not only will a good intake give your WRX STI more breathing room, but they look awesome under the hood. When it comes to performance air intakes, AEM, Injen, and Cobb are top brands that immediately come to mind.

Suspension: Tighten Things Up, Take on Corners Like a Champ

One of the biggest weaknesses of the WRX STI is its stock suspension. A simple upgrade like lowering springs or coilovers can make your Subaru feel like a whole new beast. This dramatically improves handling, especially in the corners.

While coilovers like ISC Suspension offer tons of adjustability, a good set of lowering springs like those made by Eibach or Swift can help dial things in. No more excessive body roll.

Brakes: Slow Your Roll with Confidence

When you increase your WRX STI's performance, you need a good way to slow it down. I decided to go with the StopTech Big Brake Kit and have been delighted with them.

This provides improved stopping power, which helps me feel more confident behind the wheel, especially during those spirited drives. There's nothing more important than safety.

High-performance brake pads and upgraded rotors from companies like Hawk or Brembo will give you improved braking performance. This means shorter stopping distances, reduced brake fade, and better control on the track or those curvy roads we all love.

Exterior Mods: JDM Style for Days

Making sure your 2015-2021 WRX STI looks the part is just as important. This means turning that rally-inspired look into a full-blown JDM (Japanese Domestic Market) inspired machine. For instance, carbon fiber is very popular.

Carbon fiber is cool not just because it looks amazing but also because it significantly reduces the car's overall weight compared to traditional steel. Aside from hoods, other exterior mods such as spoilers, lips, and diffusers can add a ton of personality and completely transform your car. It's your car - make it yours.

Wheels and Tires: Completing the Look

When choosing a good set of aftermarket wheels, always prioritize quality. There is no point in cheaping out here because you'll eventually have problems down the road.

A lightweight set of wheels wrapped in high-performance tires will not just complement your car's looks but also play a critical role in how well your car accelerates, handles, and brakes. 

Whether it is your first time diving into modifications or you are a seasoned veteran on the track, finding high-quality 2015-2021 Subaru WRX STI aftermarket parts is only half the battle. Always choose reputable brands known for their quality and performance. Doing your due diligence on the products, the manufacturers, and installers will go a long way in making sure you have a great experience.

More importantly, always remember to prioritize reliability, compatibility, and safety in all your modding decisions because a fast car is nothing without a safe driver. After all, what is the purpose of those amazing 2015-2021 Subaru WRX STI aftermarket parts if you don't use your car the way Subaru intended? So buckle up (and maybe invest in a good helmet) and get ready to experience the sheer thrill of driving a well-tuned WRX STI.
