The subframe on your 370Z / G37 is designed to blend comfort with performance, using soft rubber bushings on all four mounting positions. These bushings work well for a car driven in a stock environment, but when your car is subject to the harsh power transfer that takes place in drifting, circuit, or drag racing they leave a bit to be desired. Solid subframe bushings are available, but changing these is no easy feat and requires that the subframe is completely removed and factory bushings are cut out, and the comprimises they bring make them less than ideal for most street or dual use cars. This is an expensive and time consuming repair.

Keeping these challenges in mind the Z1 R&D team put their minds to work and began developing a simple and cost effective, yet easy to install solution. 

Why is subframe rigiditiy important?

Maintaining subframe rigidity in relation to the chassis helps maintain suspension geometry when under suspension load or drivetrain torque, helping reduce harsh and harmful wheel hop. Z1 Subframe Bushing Collars take up slop developed by old stock rubber subframe bushings, to yield a more responsive and direct suspension while reducing wheel hop on aggressive launches.

These 8 piece aluminum collars install above and below each of the four bushings and retain the stock anti-squat geometry. Installation can be completed in your driveway without any special tools, making this the most cost effective solution. Because OEM rubber bushings are retained this offers minimal compromise in driving comfort and NVH.
