Alpha-N G87 M2 Carbon Rear Underbody Floor Kit

The Alpha-N G87 M2 Carbon Rear Underbody Floor Kit brings true motorsport-inspired aerodynamic engineering to the latest generation BMW M2. Developed and manufactured in Germany by Alpha-N, a carbon fiber specialist with extensive motorsport experience, this rear underbody system enhances both the performance capability and visual aggression of the G87 platform.

Designed as a two-piece aerodynamic system intended to work in combination with Alpha-N’s carbon rear diffuser and CSL trunk configuration, the rear underbody floor kit improves airflow management beneath the rear of the vehicle. By smoothing airflow under the chassis and directing it toward the rear diffuser area, the system helps reduce drag while increasing rear-end stability at speed.

The design follows the factory body lines of the G87 M2 while dramatically increasing the motorsport character of the rear of the vehicle. The extended underbody panels create a more continuous aerodynamic surface, improving airflow efficiency while visually complementing aggressive rear aero upgrades.

Each underbody floor kit is manufactured from premium pre-preg carbon fiber using a classic 2x2 twill weave. The lightweight construction maximizes rigidity while minimizing unnecessary weight. The system ships with a gloss clear-coated finish and includes mounting hardware for installation, allowing the components to be installed immediately while showcasing the deep carbon fiber weave. Matte clear coating options are also available upon request.
