ISR Performance Full Subframe Solid Inserts - Nissan 350z/Infiniti G35

This kit includes solid subframe inserts from ISR Performance, designed for the Nissan 350z and Infiniti G35. These inserts replace the factory rubber bushings in your subframe, offering a more direct connection between the chassis and the subframe.

By eliminating the flex inherent in rubber bushings, these solid inserts help to improve the car's handling characteristics. You'll notice a more responsive feel during cornering and acceleration, as the suspension geometry stays more consistent under load. This can be a significant improvement for drivers looking to get the most out of their car's suspension, especially during spirited driving or track use. The solid construction means they are built to last and will maintain their stiffness over time.

When installing these, be prepared for a more direct transfer of road noise and vibration into the cabin, as the rubber was previously isolating those inputs. This is a common trade-off for the improved handling response that solid bushings offer.
