Our engineers have combined the advantages of race spec camber plates and spherical bearings with a bearing similar to those of an OEM that isolates spring movement from the rest of the coilover assembly. We use a high-quality radial Koyo Japan bearing that integrates into the upper spring perch. Now when the coilover assembly turns, the radial bearing allows the camber plate and piston shaft to spin separately from the coilover assembly. This eliminates approximately 95% of the noise associated with camber plates on a strut vehicle. You may occasionally experience spring noise with our new radial bearing mounts, but will still notice a great improvement, since you will now enjoy the benefits and adjustability of a true race setup while not experiencing frequent and harsh spring binding noise.
