This ///M Performance Style Rear Diffuser for your BMW F30 is made from forged carbon fiber! It is designed to fit 3 Series sedans with the M-Sport package or retrofitted M-Sport rear bumper. Be sure to select Single Exhaust Cutout for 328i/330i and Dual Exhaust Cutout for 335i/340i. Dual Exhaust Cutout is also offered in a Brake Light Variant. 

The ///M Performance Style Rear Diffuser adds aggressive fins and gives your BMW that OEM+ look. This pairs perfectly with our MP or M4 Style Trunk Lips. 

Our Brake Light option adds a lower brake light for better visibility at night, in the rain, or on the track. Wiring is included and comes pre-installed to the diffuser. Taping into your existing taillight wiring is required. 

At Absolute Carbon, we have no doubt our products will make your ride stand out from the rest! If you're tired of seeing 2x2 twill weave on everyone else's BMW, step up to the supercar look and feel of forged carbon fiber!
