Real carbon fiber diffuser extensions that bolt to your factory rear bumper for GT Concept aggression. Two-piece construction delivers the downforce-ready look without compromising fitment or requiring cutting. Carbon fiber sheds weight while resisting road heat and UV exposure.
Do I need to apply clear coat, or does this come finished?
These arrive in raw carbon fiber without a protective clear coat applied. Sand and prep the surface lightly, then apply your chosen automotive clear coat to lock in the weave detail and shield against UV fading over time. This also gives you control over the final finish — matte, satin, or gloss.
What prep work is required before installation?
Fit-check the pieces against your rear bumper before final fastening. Align both spats for even gaps, then drill or bolt per your vehicle's existing attachment points. Verify clearance between the extensions and any exhaust tips or undertrim to avoid contact during suspension movement.
Will raw carbon fiber yellow or degrade in the sun?
Unprotected carbon can develop a cloudy UV haze over months of direct sunlight exposure. A clear coat layer (automotive grade, UV-stable) applied before installation prevents this and keeps the weave sharp and glossy. This is a one-time step that pays off long-term.
