Frequently Asked Questions
Transform the rear profile of your Audi RS7 C7 4G Sportback with this premium dry carbon fiber rear bumper diffuser, precision manufactured using a 3D design and CNC milling process with full autoclave curing. Styled after the factory OE profile and designed specifically for the RS7 C7 4G factory rear bumper, this diffuser introduces a purposeful aerodynamic visual element to the lower rear bumper — visually widening and lowering the rear stance while delivering a more aggressive, motorsport-inspired rear-end presence. Dry carbon fiber construction offers a superior strength-to-weight ratio, tighter weave consistency, and more refined surface quality compared to standard wet carbon alternatives. The high-gloss epoxy polished surface maintains the deep gloss dry carbon finish over long-term outdoor and driving exposure. Mounting screws are included for a secure and precise installation.
