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.
