The Toyota GR86 and Subaru BRZ are blank canvases that are begging to be personalized. These rear-wheel-drive compact sports cars are cult favorites in the tuning scene, and for good reason—the aftermarket support is insane. With parts and kits everywhere you look, you can build your dream setup. But here's the truth: modding doesn’t have to bleed your wallet dry. You can still stack up solid performance and style upgrades without dropping a grand.

Ready to make your GR86 or BRZ stand out? These are the best GR86/BRZ mods under $500 that actually deliver.

1. Perrin Cold Air Intake ($419.90)

The Perrin cold air intake is a functional beast that relocates the filter behind the front bumper, far from all that engine heat. Translation? Cooler air, more oxygen, and more power. Expect a bump of 7–10 wheel horsepower with zero compromise on reliability. No tune required. It also unleashes a deep, throaty growl that screams performance every time you floor it.
