Carbon Fiber Rear Valance for 10-12 Audi S4 & A4 S-Line [B8]

Designed and manufactured to improve performance and everyday drivability, DEVAL aerodynamics offers integration between style and performance. Proven on the race track, DEVAL body kits are trusted by professionals to improve airflow & handling on their race car. Each DEVAL product is made with the optimal material to utilize its specific advantages - making it comfortable on the track or on the streets.

NOTE: Like all Carbon Fiber and FRP products on the market, this product must be test fitted & prepped before installing it. Often, slight modifications are required such as trimming, sanding, filing, or smoothing the surface in order to get best fitment and appearance. This is NOT an OEM product, fitment will NOT always be perfect straight out of the box. We recommend having this product installed by a company that has experience working with AFTERMARKET body kit pieces, not a standard collision repair center that only works on insurance claims. Images below show an accurate representation of THIS PRODUCT, properly installed by a professional installer. We also install this product at our own installation facility in southern California.
