Protect Your Subaru From The Elements with GrimmSpeed Mudflaps
A Simple Yet Crucial Upgrade
When it comes to owning a Subaru, a big part of the fun is driving it the way it was meant to be driven. Whether you’re on a gravel back road, commuting through rain, or just cruising to your favorite weekend spot, your car is constantly battling road debris. Mudflaps might not be the first thing you think of when planning upgrades, but they’re one of the smartest ways to keep your Subaru looking clean and protected.
At GrimmSpeed, we’ve seen first-hand what unprotected rocker panels and fenders look like after years of road spray. Paint chips, scratches, and baked-on grime add up quickly. A proper set of mudflaps stops rocks, water, and dirt from blasting into your paint and trims, all while giving your WRX or STI a sharp, rally-inspired look. That’s why we set out to create a kit that not only works but also installs easily and lasts as long as your car.
Built to Last
A mudflap is only as good as the materials it’s made from. Cheap plastic flaps can warp, crack, or fade, leaving you with more problems than solutions. GrimmSpeed Mudflaps are constructed from 98A Shore polyurethane, a material that’s stiff enough to block debris but flexible enough to resist cracking when the temperatures drop. Each flap is designed to hold its shape through years of daily driving and harsh conditions.
Backing them up are 304 stainless steel mounting brackets for strength, paired with Magni-coated stainless hardware that resists corrosion while blending in with your Subaru’s bodywork thanks to its black finish. Every piece was chosen with durability and clean looks in mind.
Designed for Easy Installation
Nobody wants to spend hours drilling into their car just to install mudflaps. That’s why our kits are engineered for a direct bolt-on fit using factory clip holes. No cutting, no drilling, no headaches. The end result is a factory-clean install that you can trust.
Every kit includes the hardware you’ll need for all four corners of the car, with brackets and fasteners carefully matched to each location. It’s a complete package; open the box, grab a few basic tools, and you’re ready to go.
A Look That Fits Your Style
Function is important, but we know that looks matter too. GrimmSpeed Mudflaps bring a rally-inspired edge to your Subaru without being over-the-top. Each flap comes finished with the GrimmSpeed logo, and you can choose between red or white lettering to match your ride’s aesthetic.
