Alpha-N Carbon Rear Underbody for G87 BMW M2
The carbon rear underbody floor kit, designed as a two-part system in conjunction with Alpha-N’s new G87 M2 carbon rear diffuser, is also intended to work seamlessly with the CSL trunk lid. This package is engineered to both enhance downforce and reduce drag. By following the G87 M2’s natural body lines, the rear diffuser and underbody floor kit add an aggressive touch to the vehicle’s rear styling. Made from pre-preg carbon in a 2×2 weave, the kit offers minimal weight and maximum strength.
