Do these over fenders require any special hardware to install?

These ship as bare FRP panels without fasteners included. Installation method depends on your chosen mounting strategy — verify your vehicle's existing fender bolt locations and drilling needs before purchase. Many builders use through-bolts or adhesive tabs; reference your service manual or installation guide for the approach that matches your setup.

What surface prep is needed before paint?

Sand and prep the surface with standard finishing techniques before applying your chosen primer and paint. FRP accepts most automotive finishes, but clean all release agent and dust beforehand to ensure proper adhesion.

Will these fit if I've modified my suspension or wheels?

Over fenders add width but do not change ride height or suspension geometry. If you've lowered the vehicle significantly or run much wider wheels, measure your tire clearance against the fender line in your actual setup before committing to installation. The 20mm extension is substantial enough to require verification on heavily modified builds.
