TGK Motorsport Rear Spherical Strut Perch B9/C8/C7/4M

TGK-0411-08

The TGK Motorsport Billet Rear Spherical Strut Perch replaces the factory rubber strut mount with a precision spherical bearing assembly, removing unwanted deflection while allowing the strut to articulate smoothly through its full range of motion. This rigid, billet housing paired with a PTFE-lined spherical bearing eliminates the compliance that directly affects rear suspension behavior during cornering, braking, and rapid load transitions.

The factory rear strut mount uses a rubber isolator that allows the strut to move under load, compressing and deforming when load is applied and causing the strut to shift relative to the chassis. This movement changes suspension geometry moment-to-moment, making the rear of the car less predictable and harder to control at the limit, especially on vehicles with stiffer springs, coilovers, wider tires, or increased grip.
