Not many upgrades will force you to say, "damn that's incredible" or just plain "wow." The M7 Under Strut System (USS) features three integrated pieces that will brace, connect, and triangulate the bottom of the chassis for greatly improved chassis stiffness. This improved stiffness will give the MINI better turn-in capability allowing the car to rotate into the corners with ease, and also greatly reduce understeer.The M7 Under Strut System is made of extruded and CNC machined aluminum that comes in a black anodized finish that’s durable and designed to prevent chipping and corrosion. Stainless steel fasteners and necessary tools for nut insert installation are all included! We’d say our months of rigorous testing at local race tracks, treacherous canyon roads and sweeping on/ off-ramps, were a good investment—just the same thing you’ll think about the M7 USS.

Price is $349 shipped in the US.
