Like most modern cars, under performance driving the BRZ/FR-S suffers from significant chassis flex and wheel hop. Under hard acceleration, the stock sub frame moves quite a bit, reducing stability. The Hotchkis Sport Suspension Brace for the Scion FR-S/Subaru BRZ reduces chassis flex and improves high-speed cornering by triangulating the shock towers with the firewall. Manufactured from strong, lightweight 6061 T-6 1.5" x 3/4" aero extruded tubing and mated to laser cut, CNC machined aluminum brackets, the system bolts on in minutes.
