Aggressive rear diffuser in fiberglass-reinforced plastic, designed to add visual depth and definition to the rear bumper area. Requires Surface Prep, ready for your chosen finish. One-piece construction keeps installation straightforward and fitment clean.
Will this diffuser scrape on steep inclines or driveways?
JS-profile diffusers sit closer to the factory bumper plane than aggressive aero pieces, minimizing scrape risk on typical entrance angles. Check your vehicle's current ground clearance at the rear bumper and measure the diffuser's extension before installation to confirm fit with your local driveway geometry.
Is this purely cosmetic or does it provide functional downforce?
This diffuser is styled after performance aesthetics and adds visual aggression to the rear end. Functional aerodynamic benefit depends on vehicle speed and overall aero package balance — for track use, pair it with complementary front aero elements for balanced airflow.
What prep work does the FRP need before painting?
Sand the surface with appropriate grit to promote paint adhesion, wipe clean to remove dust, and apply your chosen primer and topcoat system. FRP accepts standard automotive paint finishes — follow your paint manufacturer's prep guidelines for best results.
