Sharpen the rear profile of any G8X chassis—sedan, coupé, or convertible—with autoclave-cured, 100 percent dry carbon fiber extensions. Compared with wet-lay alternatives, dry carbon delivers aircraft-grade rigidity, feather-weight mass, and a perfectly uniform matte weave.
Swap them in minutes: unclip the factory diffuser extensions and snap the new pair into place—no cutting, drilling, or adhesives required. Each kit includes driver- and passenger-side replacements engineered for OEM-grade fitment that hugs the stock bumper contours.
