Audi A5 S-Line/S5 B9 Carbon Fibre Rear Bumper Diffuser Splitters

Redefine the rear presence of your Audi with this precision-crafted carbon fibre rear bumper diffuser and splitter set. Designed to complement the aggressive S-line and S5 Sport aesthetic, this piece adds a purposeful, track-inspired edge that transforms an already striking rear end into something truly commanding.

Hand-laid from high-quality carbon fibre and finished to a deep, lustrous gloss, this diffuser delivers the kind of visual drama that turns heads at every angle. The intricate weave pattern catches the light beautifully, adding depth and sophistication to the lower rear fascia while reinforcing the car's performance character.

Precision CNC moulding ensures a seamless, OEM-grade fitment across both two-door and four-door body styles — no cutting, no modification, no compromise. Every panel is test-fitted on real vehicles before leaving the facility, so you can install with complete confidence.

Elevate your Audi's stance and style with a component engineered to impress. Add to your build today and experience the difference that genuine carbon fibre craftsmanship makes.
