If you're building your B9 the right way, the rear end matters just as much as the front. This Prepreg Dry Carbon Fiber Rear Diffuser is designed to give your Audi A4 S-Line or S4 a sharper, more aggressive finish that completely transforms the rear profile. The 3D-contoured design adds depth, dimension, and true performance-inspired styling — giving your build that finished, high-end look it deserves.
Crafted using advanced prepreg dry carbon construction and autoclave curing, this diffuser delivers exceptional strength with lightweight performance. The deep gloss epoxy finish enhances the carbon weave clarity while protecting against UV exposure and surface wear. Whether you're going for a subtle OEM+ upgrade or a full performance aesthetic, this diffuser ties the entire rear bumper together with precision styling.
Upgrade your B9 with carbon that speaks for itself. Clean lines, aggressive styling, and premium construction — this is the rear-end detail your build has been missing.
