Audi A6 S-Line / S6 C7 Avant Carbon Fiber Rear Bumper Diffuser Lip 2015 - 2018

Transform the rear profile of your Audi A6 S-Line or S6 C7 Avant with this premium carbon fiber rear bumper diffuser lip, precision manufactured using a 3D design and CNC moulding process with full autoclave curing. Designed as a direct-fit retrofit upgrade for the A6 S-Line and S6 Avant factory rear bumper, this diffuser lip introduces a purposeful aerodynamic visual element to the lower rear bumper — visually lowering and widening the rear stance while delivering a more aggressive, motorsport-inspired rear-end presence. Carbon fiber construction offers a superior strength-to-weight ratio, consistent weave pattern, and refined surface quality that perfectly complements the factory Avant bodywork. The high-gloss epoxy polished surface maintains the deep carbon finish over long-term outdoor and driving exposure. Adhesive tape is included for a clean, no-drill installation with no permanent modification required to the factory rear bumper.

• Premium carbon fiber construction – autoclave cured using 3D design and CNC moulding, delivering superior resin consistency, tighter weave pattern, and refined surface quality
