PRE-ORDER, FEB 2026: Z33 R-tune anti-hop differential carrier bushing

Developed to emulate a NISMO R-tune S15 differential carrier bushing, with a stiffness target tailored for the Z33's single rear mount. Features ADOPT specification high-hysteresis polyurethane formulation to adequately dampen and suppress axle-hop without introducing the deafening NVH of the typical solution, a solid metallic bushing.

The only double-bonded polyurethane bushing on the market, which addresses tilting failure modes/kinematics that all other products ignore. Single-sided polyurethane products are cheap, but they can move and distort in the subframe bore temporarily under high loads and hot temperatures; they also exhibit creep and become permanently distorted under repeated high cycle loads. This bushing is properly supported in a steel sleeve with high shape factor of bonded area, spreading load over a much larger bond area, preventing deformation.

Designed using methodology of SAE technical papers from J.M. Horton, et al.
