R33 SPL Solid Subframe Bushings

Our slide-in shim system allows you to quickly raise or lower the subframe to fine-tune the roll center/anti-squat behavior to your preference. Raising the subframe will compensate roll center for a lowered car at the expense of increasing anti-squat. Lowering the subframe will decrease anti-squat at the expense of roll center.

Our SPL SOLID series bushings are precision CNC machined from billet aluminum for an accurate fit. Kit also includes optional rubber isolation washers to reduce noise transfer from the subframe to the chassis.
