SPL Parts solid aluminum rear subframe bushing kit replaces the stock mushy rubber bushings on your Scion FR-S and Subaru BRZ. This eliminates free play of the rear subframe relative to the chassis and reduces the "bouncing" of the rear axle housing under drivetrain torque and suspension load, maintaining optimum suspension geometry and reducing wheel hop.
SPL's slide-in shim system also 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.
Now Formula Drift Regulation Compliant. This kit was altered from the original version to fit changes in Formula D. You can maintain OEM height and be perfectly legal.
SPL Parts Solid series bushings are precision CNC machined from billet 6061 Aluminum for an accurate fit. This kit also includes optional rubber isolation washers to reduce noise transfer from the subframe to the chassis.
Sold as a complete kit for one car. Made in the USA.
