Stage 2 Chassis Reinforcement Kit

The M7 Speed Stage 2 Chassis Reinforcement Kit is a performance-oriented upgrade designed to significantly improve the handling dynamics of Gen 1 MINI Cooper models (R52S & R53S). This kit, which includes the Under Strut System (USS) and the Rear Chassis Brace, aims to transform the vehicle's cornering capabilities by increasing chassis stiffness. A stiffer chassis is crucial for optimizing the performance of other suspension components like springs, shocks, and sway bars. By reducing chassis flex during hard cornering, this kit ensures tires maintain better contact with the road. The M7 Under Strut System braces, connects, and triangulates the lower chassis, while the Rear Chassis Brace addresses flex in the rear end. Together, they contribute to maximum grip, enhanced steering response, and reduced understeer, particularly during aggressive maneuvers or emergency situations. The kit comes complete with stainless steel fasteners and necessary tools for installation. The M7 Speed Stage 2 Chassis Reinforcement Kit is engineered, tested, and proven to perform, offering a noticeable improvement in vehicle stability and driver feedback. Installation notes indicate that proper drilling technique is critical for the Under Strut System. Ensure you have adequate clearance and can drill perpendicular to the underbody to avoid installation issues. Additionally, there may be fitment conflicts with certain Milltek and Alta exhaust systems. The Rear Chassis Brace is noted to fit the R53 Hatchback only.
