Description
Take your MINI’s handling to the next level with the M7 Speed Under Strut System (USS) — the ultimate underbody chassis reinforcement kit for Gen 2 MINIs. Designed and tested extensively, this system significantly improves chassis rigidity, delivering sharper cornering, reduced understeer, and increased driving confidence.
Developed as the successor to the popular R53 USS, the M7 R56 Under Strut System connects and triangulates the underside of your MINI with three precision-engineered braces (two front, one rear). The result is a stronger, stiffer chassis that transforms your car’s agility and stability, both on the street and track.
