Enhance the rear of your BMW M3 G80 | M4 G82/83 with the new VR Aero carbon fiber rear diffuser. Carbon fiber diffusers have been a popular upgrade for many years on almost all the BMW M3 variants. Its a great way to further accentuate upgraded exhaust systems and give the M car a more stout look. The VR Aero carbon fiber rear diffuser for the BMW M4 was designed utilizing 3D scanning and CAD programs. VR Aero set out to achieve perfection by delivering precise fitting carbon fiber that requires no modification to install. The elegant 2x2 (3K Twill Weave) will grab your eyes and draw you closer to the glossy finish that shows the depth of the weave. Using pre-preg carbon allows for the rear diffuser to have a sturdy construction while giving it the lightweight property everyone knows and loves. VR Aero matches the OEM quality that BMW M4 G82 owners insist on by bringing the best product to the market. UV-resistant epoxy eliminates the chances of the rear diffuser getting yellow and hazy over time. Commonly seen in cheaper carbon fiber, a yellow haze can form after being exposed to UV rays. The glossy clear coat also adds another layer of protection against the elements. Features: 3K 2x2 twill-weave construction Pre-preg dry carbon fiber is 60% lighter and significantly stronger than standard layups. Utilization of 3D modeling offers superior fitment The autoclave process increases durability and longevity UV resistant resin prevents yellowing and hazing of the fibers Marvelous shine thanks to the glossy clear coat OEM-Plus manufacturing and appearance No modification is required for installation
