DTM Fiber Werkz BMW F10 5-Series Rear Diffuser For Mtech Bumper [FRP/CFRP]

Compliment the Mtech rear bumper of your BMW F10 5-Series with this Rear Diffuser for use with the Mtech bumper from DTM Fiber Werkz. This rear diffuser adds a little extra visual ""edge"" to your 5-Series' rear. Produced in fiberglass reinforced plastic [FRP] for superior strength and durability compared to traditional fiberglass and this diffuser comes unpainted and finished in a gelcoat, ready to prep, prime and paint to match your vehicle. This diffuser is also available in full carbon fiber construction (+$200.00) for a bold visual statement and superior strength. Vehicles shown may include moldings, grilles or an addition to the DTM Autowerkz piece. Parts such as lights, splitters, canards, paint, grilles and other accessories are not included unless specified.

AttentionNOTE: 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, filling, or smoothing the surface in order to achieve the best fitment and appearance. This is NOT an OEM product, fitment will NOT always be perfect straight out of the box. We strongly recommend having this product installed by a body shop experienced in working with AFTERMARKET body kit pieces, not a standard collision repair center that works on insurance claims. Images for this item are an accurate representation of THIS PRODUCT, properly installed by a professional installer. We also offer installation of this product at our own installation facility in southern California
