What prep work do I need to do before installation?

Sand the mounting surface on your factory fenders to remove any wax, dirt, or old coating. This ensures the over fenders sit flush and any adhesive or fasteners bond correctly. After mounting, sand the primed FRP surface with 220-grit or finer before applying your color coat.

Do these over fenders require drilling into my factory fenders?

Yes. Over fenders bolt to the existing fender structure. Mounting holes will need to be drilled through both the factory fender and the over fender panel. Mark your hole locations carefully using the over fender as a template to ensure proper alignment before drilling.

Will these work with my current wheel and suspension setup?

The 30mm width extension is designed to accommodate wheel fitments that sit wider than stock. Verify that your current offset and tire size do not already tuck inside the factory fender—if they already fit, the over fenders serve as a styling upgrade rather than a functional necessity. Test fitment in the corners and under full suspension compression before final installation.
