The K-Brace is the best value under strut on the market. Using the same stock bolt on points that Dr. Mike of the former TSW found to be best we have created the K-Brace. Link here Auto X Cooper Like the other systems it improves overall handling of the MINI by adding braces that connect and triangulate to the weak end of the stock sub-frame helping reduce the twisting motion that happens with torsional loading of the chassis in corners. The K-Brace gives the MINI better steering response, better turn-in, rotation and reduces under steer when you want it. Under load in corners it gives you more control with less drama when the road under you changes. The K-Brace gets better with speed and gives you that edge you want.
