Overview
Protect your Subaru and keep it looking sharp with GrimmSpeed Mudflaps. Designed specifically for the VA-chassis WRX and STI (2015–2021), these flaps shield your paint from rocks, water, and road debris while giving the car a purposeful, rally-inspired look. Engineered for a direct fit, they mount cleanly to existing factory clip holes, no drilling required.
Unlike flimsy plastic alternatives, our mudflaps are built from high-durometer polyurethane that balances flexibility and strength, ensuring they won’t crack, warp, or fade. Pair that with stainless steel brackets and corrosion-resistant hardware, and you’ve got protection that’s built to last. To top it off, each flap is finished with the GrimmSpeed logo, available in either red or white lettering to match your style.
From the material choice to the hardware finish, every detail of these mudflaps was considered with long-term performance in mind. They install easily, look clean, and stand up to daily driving or weekend track days.
