Rear suspension holders are separated from the bulkheads and installed on the chassis. Mounting the holders directly to the chassis plate eliminates any flex from the bulkheads, improving the precision and responsiveness of the GT.

The rear holders still offer multiple anti-squat positions, but the redesigned plates have less anti-squat, which is better suited for the GT category to increase the stability of the car.

The aluminum suspension holders continue to feature the Integrated Suspension Settings (I.S.S.) that allows for quick & easy suspension geometry changes

Using the eccentric suspension bushings inserted into aluminum suspension holders, and a few suspension shims, the GTX suspension geometry can be completely adjusted in seconds.
