FRS/BRZ solid aluminum subframe bushings replace the stock mushy rubber bushings on your Scion FR-S and Subaru BRZ to eliminate free play of the subframe relative to the chassis. This prevents the subframe from "bouncing around" under drivetrain torque or suspension load, maintaining optimum suspension geometry and reducing wheel hop. 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. Now Formula Drift Regulation Compliant! With the recent regulation change in Formula D, we changed our kits to comply. You can maintain OEM height and be perfectly legal. Our SPL 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.
