Overview

The GKTech Z33 350z/G35 rear subframe collars are an 8-piece set designed to eliminate axle tramp and tighten the rear end for more precise control.

These collars fill the voids within the factory subframe bushes, making the subframe feel more integrated with the car. They are manufactured from a proprietary 90sHA material.
Show original supplier description
The GKTech Z33 350z/G35 rear subframe collars are designed to enhance vehicle control by eliminating axle tramp and tightening the rear end. These collars are intended to replace the OEM bushes, which are often optimized for comfort rather than performance, by filling the voids within the factory subframe bushes. This modification results in a more unified feel between the subframe and the car. Constructed from a proprietary 90sHA material, this 8-piece set offers a noticeable improvement in rear-end stiffness and accuracy. Unlike a full solid subframe bush conversion, these inserts are significantly easier to install and do not drastically affect the vehicle's noise levels, though some increase in NVH may be noticed if the vehicle is not already equipped with coilovers or other performance parts. Installation is straightforward, requiring no modifications. The process involves loosening the subframe while supporting it, slipping in the collars, and re-torquing the subframe. Existing subframe hardware can be used. The installation is estimated to take approximately 45 minutes. These rear subframe collars are compatible with the Z33 350z (2003-2008), G35 Coupe (V35, 2003-2007), and G35 Sedan (V35, 2003-2006). Note that the 2007-2008 G35 (V35) Sedan uses Z34 370z/G37 (V36) suspension components.
