SPL CNC machined T6061 aluminum subframe bushings completely replace the stock bushings to eliminate free play of the subframe relative to the chassis, reducing wheel hop and improving suspension performance. SPL's new version 2 solid subframe bushings is designed to allow the subframe to sit up to 1/2" closer to the chassis (raising the subframe), which will allow up to 1/2" compensation of roll center for a lowered car.

However raising the subframe will not just change roll center, it will also increase anti-squat. Therefore SPL subframe bushings include 1/4" slide in shims so you can quickly raise or lower the subframe in minutes, and adjust the roll center and anti-squat behavior to best fit your driving style! SPL unique adjustable subframe bushings offer a completely new way to tune the suspension behavior.
