MMX Underbody Chassis Brace - F80, F82, F83, F87
$295.00

The MMX Performance Underbody Chassis Brace is engineered specifically for the F8x platform to eliminate the unwanted flex that plagues the factory mid-section. On the track or your favorite backroad, flex alters your alignment mid-corner, reducing tire contact patch. The MMX brace replaces the weak OE bracing with a highly rigid, billet aluminum structure. This ensures your suspension components do the work they were designed to do, delivering superior feedback through the steering wheel. If you are looking to extract the absolute maximum performance out of your M2, M3, or M4, this is a crucial upgrade for your chassis setup.

Key Features:

  • Maximizes rigidity to maintain precise suspension geometry under load

  • Engineered from solid billet aluminum to withstand extreme load

  • Directly replaces the weak, flex prone factory underbody support panels

  • Precision engineered for an exact, zero-modification fitment using factory mounting points

  • Optimized geometry provides maximum reinforcement without sacrificing ground clearance

Specifications:​

  • Material: Billet T6-6061 Aluminum

  • Finish: Anodized Anti-Corrosion Coating

  • Application: Chassis Reinforcement / Track & Street
