The Ultimate Guide to Modifying Your Subaru: Boost Performance and Aesthetics!

Subaru vehicles have always been known for their reliability and versatility, making them a favorite among car enthusiasts. With their all-wheel drive system and potent turbocharged engines, it’s no wonder why Subaru owners are passionate about modifying their vehicles. In this guide, we’ll cover the essential and advanced aspects of Subaru modding, catering to beginners and experienced modders alike.

Why are Subaru mods popular?

Subaru mods are popular among car enthusiasts for several reasons. One of the main reasons is the potential for performance-enhancing upgrades. Many Subaru models come with powerful turbocharged engines, but with the right modifications, the power output can be increased even further. Additionally, Subaru’s all-wheel-drive system provides excellent handling and grip, making it an excellent platform for suspension upgrades and other chassis modifications.

Subaru mods are also popular because of the variety of models available, allowing modders to choose a vehicle that suits their specific needs and tastes. Whether it’s the rally-inspired WRX or the family-friendly Outback, the range of Subaru models provides a wide range of options for modding.

Engine Upgrades

One of the most popular modifications for Subaru vehicles is engine upgrades. There are several ways to increase the power output of a Subaru engine, ranging from simple modifications to more complex upgrades.

Intake and Exhaust Upgrades

One of the simplest modifications that can be made to a Subaru engine is upgrading the intake and exhaust systems. Increasing the amount of air flowing into the engine and optimizing the outflow of exhaust gases can lead to improved performance. Cold-air intakes and high-performance exhaust systems can improve the airflow and increase power output.

Turbo Upgrades

For those looking to take their Subaru’s power output to the next level, upgrading the turbocharger is a popular option. Turbo upgrades can provide a significant increase in power and performance, but they require some more technical knowledge and installation experience.

Engine Tuning

Engine tuning involves optimizing the engine’s software to increase power output while maintaining reliability. This can be done using stand-alone engine management systems or through a reflash of the factory ECU. Engine tuning requires technical knowledge and should only be attempted by experienced modders.

Suspension Upgrades

Subaru’s all-wheel-drive system provides excellent handling and grip, but adding suspension upgrades can further improve its handling capabilities. Suspension upgrades can improve steering response, reduce body roll, and increase grip when cornering.

Lowering Springs

Lowering springs can lower the vehicle’s center of gravity, which can improve handling by reducing body roll. Lowering springs are relatively inexpensive and easy to install.


Coilovers are a suspension system that allows for adjustable ride height and damping. Coilovers provide superior adjustability compared to lowering springs but with a higher price tag.

Brake Upgrades

Increased power output and improved handling capabilities mean that upgrading your Subaru’s brakes is crucial to ensure safety and performance. Upgrading the brakes can improve stopping power, reduce brake fade under heavy braking, and provide more consistent brake performance.

Brake Pads and Rotors

Upgrading the brake pads and rotors can improve overall braking performance. High-performance brake pads can withstand higher temperatures and provide more stopping power, while upgraded brake rotors can improve cooling and provide better bite.

Brake Calipers

Upgrading the brake calipers can improve braking performance by providing a more rigid and powerful braking system. Some brake calipers also have larger pistons, which can provide more stopping power.

Aesthetic Changes

Subaru mods aren’t just about performance; they’re also about making your vehicle look good. There are several aesthetic modifications that can be made to your Subaru to make it stand out from the crowd.

Wheels and Tires

Wheels and tires are one of the most visible modifications that can be made to a Subaru. Besides improving the vehicle’s aesthetics, upgrading to bigger or wider wheels and tires can improve handling and grip.

Body Kits and Spoilers

Body kits and spoilers can enhance the vehicle’s styling while also providing aerodynamic benefits. Body kits can change the vehicle’s appearance, while spoilers can provide more downforce, improving grip and handling.

Subaru Models and Mod Suitability

Different Subaru models are better suited for specific modifications. Some models, like the WRX and STI, have a wide range of aftermarket support and are easy to modify. Other models, like the Legacy and Forester, have fewer aftermarket options but still provide potential for upgrades.


Can I modify my stock Subaru without risking reliability?

Yes, modifications can be made to your Subaru without risking its reliability. However, it would be best to research and consult with experienced modders to ensure that the modifications are appropriate for your vehicle and that they’re installed correctly.

Simple modifications such as intake and exhaust upgrades can cost a few hundred dollars, while more complex upgrades such as engine tuning or turbo upgrades can cost several thousand dollars.

Do all modifications increase my Subaru’s power output?

No, not all modifications increase power output. Some modifications, such as aesthetic changes, do not affect performance.


Subaru mods can enhance your vehicle’s performance, handling, and aesthetics. With the range of aftermarket options available, there is a modification for every taste and budget. Remember to research and consult with experienced modders before making any modifications to your vehicle.
