Description
The Alpha-N Carbon Rear Underbody Floor Kit is designed to fit the BMW M2 G87 2023+, and is available in Australia through iilumolab. Developed and manufactured in Germany by Alpha-N Performance, a brand with deep roots in BMW motorsport, this two-piece underbody system brings true motorsport-inspired aerodynamic engineering to the latest M2 platform.
Designed to work in combination with the Alpha-N Carbon Rear Diffuser, the underbody floor kit smooths airflow beneath the rear of the vehicle and directs it toward the diffuser area reducing drag and increasing rear-end stability at speed. The extended underbody panels create a more continuous aerodynamic surface, improving airflow efficiency while visually complementing aggressive rear aero upgrades.
Each underbody kit is constructed using pre-preg 2x2 twill carbon fibre sourced from Italy and finished with a UV-resistant gloss clear coat. It is ready for installation straight from the box. Mounting hardware is included. Note: this kit is designed to work with the Alpha-N rear diffuser, and the factory diffuser will require modification.
As an authorised Alpha-N dealer, iilumolab guarantees every product is 100% genuine — backed by Alpha-N's manufacturer warranty and our local Australian support team.
