Weld Semi-rigid Differential Collar (for JZX90/100/110 & Altezza)

A must-have item for Toyota JZX90, 100, 110 and Altezza owners!

This item semi-rigidifies the rear subframe and differential.

During circuit driving or sports driving, the differential bushings flex and twist, placing a significant load on the subframe. This results in judder, which not only prevents sufficient traction from being transmitted but also makes the vehicle's behavior unstable and reduces cornering performance.

By making the differential bushing area semi-rigid, the load on the subframe and bushings is reduced, allowing for stable and reliable traction. This ensures that the vehicle's inherent power is reliably transmitted to the road surface, resulting in more stable handling and improved cornering performance. Furthermore, the semi-rigid configuration of the differential and subframe provides a more direct feel and improved axle response.

Despite all these benefits, the differential semi-rigid collar is easy to install—simply insert it into the differential bushing on the rear member and tighten it with bolts!
