Underbody Chassis Braces - Set of 3 - Mini F56 F55 F54

Transform the way your Mini drives with this complete set of three MMR Underbody Chassis Braces for Mini F56, F55 and F54. These precision machined T-6061 billet aluminium braces replace the heavy steel OE braces to add chassis rigidity, improve handling, create vital exhaust clearance for larger diameter systems and deliver a tougher, cleaner underbody look. Perfect for fast road and track day Minis including Cooper, Cooper S, Cooper SD and JCW.

Why upgrade your Mini underbody braces

  • Stronger and lighter than the factory steel braces for sharper, more precise handling and stability
  • Extra exhaust clearance when fitting a cat-back or larger bore performance exhaust
  • CNC machined from billet T-6061 aluminium for strength without unnecessary weight
  • Gloss black anodised finish for durability and a premium OEM Plus look
  • Direct bolt-on fit using existing mounting points, no drilling, no trim removal, fully reversible
  • No added noise, vibration or harshness, just better control and confidence

Each brace is carefully profiled to remove excess material while retaining rigidity and ultimate strength. Rather than deleting the OE tunnel bracing, this MMR underbody bracing kit keeps crucial body stiffness and gives the clearance you need for aftermarket exhaust systems.

What you get

  • Set of 3 underbody chassis braces - front, centre tunnel and rear
  • New installation hardware included
  • Gloss black anodised finish
