FAQs
Will this rear diffuser fit my Audi A5 S5 2-Door?
It matches the rear bumper shown in the gallery for 2017-2019. Compare the valance shape in the photos with your own bumper first.
Is the carbon real?
Yes – carbon fiber with a UV-stable clear coat. Not a hydro-dipped or printed finish.
Do I need to cut the rear bumper?
No. It replaces the factory lower valance section and uses the original mounting points.
What if it arrives damaged?
Send us photos within 7 days and we will replace it. Every piece carries a 12-month warranty against manufacturing defects.
Is the weave direction consistent?
Yes – the weave is laid to follow the shape of the part, so the pattern runs symmetrically on both sides.
