What Are the Best Mods for Subaru WRX STI

Subaru WRX STI is a powerful and iconic performance vehicle with almost limitless tuning potential. The car's impressive power and performance come at a price, however, and making sure your car is running optimally and safely involves many different parts and modifications. That's why it's important to find the best mods for your Subaru WRX STI to make the most of the car's potential and ensure it's running as well as possible.

Engine Remap and Upgraded Auxillary Components

An engine remap is one of the best mods for the Subaru WRX STI. This can be done by a professional tuner and will allow you to get the most out of the car's engine, enabling it to produce more power and torque and maximize its performance potential. An engine remap should also be accompanied by upgraded auxillary components such as a high-flow exhaust, better air intake and an upgraded fuel system. These components will help ensure your car runs as efficiently as possible.

Suspension Upgrades

The suspension system of your Subaru WRX STI is another area where upgrades can make a big difference. Upgraded struts, shocks and springs can help improve handling and stability and make the car more comfortable to drive. It's also worth considering fitting an adjustable Coilover kit, which will allow you to adjust the ride height and damping of your car to suit your driving style.


The stock brakes on the Subaru WRX STI can be easily upgraded to improve braking performance. Upgraded brake discs, pads and lines will help to increase the car's stopping power, while larger calipers will help to reduce brake fade. If you're looking for the best performance, it's also worth considering fitting a brake upgrade kit to provide even better braking power.

Wheels and Tires

The wheels and tyres on your Subaru WRX STI can also be upgraded to make a big difference to the car's performance. Fitting larger wheels with wider tyres will help to improve grip and handling, while lighter wheels can help to reduce the car's unsprung weight and improve acceleration. It's also worth considering fitting a different tyre compound, which can help to improve grip in different conditions.

Proper Exhaust System

Fitting a proper exhaust system to your Subaru WRX STI can greatly affect the car's performance. A good exhaust system will help reduce back pressure and improve the engine's efficiency, giving the car a deeper, more aggressive sound. It's important to ensure the exhaust system is properly fitted and meets your car's emissions regulations.

The Bottom Line

The Subaru WRX STI is a great car that offers various modifications to customize it and make it your own. The best mods for the WRX STI depend on your personal preferences and budget, but some popular options include a cold air intake, an exhaust system, suspension upgrades, and more. Ultimately, the best mod for your Subaru WRX STI is the one that fits your needs and budget, but no matter what you choose, you'll be sure to enjoy the improved performance and style.
