The lower rear shock mounts on the E8x/E9x chassis are known for quick failure and completely falling apart when they do, which will quickly be felt in your driving experience. The combination of rubber and steel, mounted in a low pocket on the rear control arm make this a perfect mix for corrosion destroying the mount. By allowing uninhibited shock articulation and a direct connection to the lower control arm, this solid monoball design eliminates slop and improves shock efficiency, allowing for more predictable handling on the street or the track - with minimal added noise, vibration, and harshness.

The engineering team at Turner came up with a design that would increase performance covering the largest issues with these rubber bushings. The performance improvement of these mounts is primarily due to the low friction articulation allowed by the bearing, combined with the elimination of unwanted deflection. Rubber mounts do not allow for proper free damper movement and the damping affect reduces the shock's ability to control wheel end movement directly.
