Will this scrape on steep driveways or ramps?

The R1 design sits close to the bumper line without aggressive projection, so clearance is comparable to the stock M Sport bumper. Check your driveway angles and approach your vehicle as you normally would—the diffuser sits inboard of where the bumper already extends.

Does the diffuser affect exhaust tip positioning?

The diffuser wraps around and under the bumper area. Before ordering, verify your exhaust tip exit height and angle relative to your M Sport bumper—this diffuser does not modify exhaust routing. If you run custom or lowered exhaust tips, measure clearance to the diffuser's inner edge.

What prep work is needed before painting?

Sand the surface with appropriate grit to promote adhesion, then clean off all dust before applying your chosen automotive finish. The FRP surface is stable and accepts standard polyurethane or urethane topcoats.
