Part of Vorsteiner's Aero program for the G87 M2, this carbon rear diffuser comes with its own underfloor section. It changes the look of the back of the car and is built the same way as Vorsteiner's other aero parts, so it fits the factory body lines closely.
What you get
- Rear diffuser with matching underfloor piece, both in carbon fiber.
- Pre-preg carbon fiber, autoclave cured. Vorsteiner rates it 20 to 30% stiffer and stronger than an equivalent wet-layup part.
- Mixed weaves of unidirectional, 1x1 and 2x2 carbon to keep weight low while staying rigid.
- Vacuum forming that removes extra resin, cutting weight and keeping fit tight to the factory panel gaps and contours.
- Glossy finish.
