Real-world results
We have fitted many of these kits at MJ Modifications and customer feedback is consistently positive. Owners report flatter cornering, better steering feel and a more composed ride on rough UK roads with the damping set correctly. The ability to fine tune camber and rebound makes this a superb upgrade for mixed road and occasional circuit use.
