The GKTech Z33 / 350Z rear subframe slip-in collars are designed to reduce unwanted movement in the rear subframe by filling the voids in the factory rubber bushings. By effectively tightening the subframe mounting points, they help eliminate axle tramp and improve rear-end stability, resulting in more precise and predictable handling under hard acceleration, cornering, or track use.
Unlike a full solid bushing conversion, these inserts retain most of the factory NVH characteristics while still offering a noticeable improvement in chassis rigidity. Installation is simple and non-invasive, requiring no permanent modifications—just loosening the subframe, sliding the collars into place, and re-torquing. This makes them a popular “bolt-in” upgrade for Z33 350Z and V35 G35 owners looking for better performance without sacrificing daily drivability.
