At RPM Performance, we are proud to offer a precision engineered rear boot strut brace for the Mini Cooper S / JCW F56 F57

This rear strut brace is designed to significantly improve chassis rigidity and handling response by reinforcing the rear strut towers. By reducing flex in the rear end under hard cornering and acceleration, it enhances steering precision and overall vehicle stability.

Manufactured in-house by using CNC fibre laser cutters and CNC-machined components, this brace ensures strength and quality. Every detail is crafted to meet the demands of both street and track use.

Engineered with performance in mind, this brace has been FEA tested and demonstrates outstanding strength only 1mm of deflection when 1000Nm of force is applied strut to strut. This ensures consistent suspension geometry and more predictable handling under load.

Installation is simple just a few bolts and no permanent modifications required.

Importantly, this upgrade maintains the comfort of your ride, delivering performance without compromising daily drivability.

Exclusively designed to fit the Mini Cooper S / JCW F56 F57

We also have the front strut brace to match and the lower chassis braces
