Installation Notes
RC0020RZ-20 replaces the factory rear sway bar on the JZA80 Toyota Supra. Remove the original bar, clean the chassis mounting locations, install the new SuperPro polyurethane chassis bushings, and fit the bar. Connect the end links to the chosen adjustment hole. Torque all hardware to specification. A rear alignment check is not typically required but is recommended if end link angles appear unusual.
Frequently Asked Questions
- What is the difference between the 3 adjustment positions on RC0020RZ-20? The three holes vary the effective lever arm length of the bar. The outermost hole (softest) provides near-OEM roll resistance, the middle position gives a moderate increase, and the inner hole delivers maximum stiffness for track-oriented setups.
- Will RC0020RZ-20 cause understeer on my Supra? A stiffer rear bar increases rear roll resistance, which can shift the balance toward oversteer rather than understeer. Starting with the soft or middle position is recommended before moving to the stiffest setting.
- Does this bar include all mounting hardware? Yes. RC0020RZ-20 includes SuperPro polyurethane chassis bushings and mounting hardware. End links may need to be sourced separately depending on your existing setup.
- Does the Magnuson-Moss Warranty Act apply to sway bar upgrades? Yes. Under the Magnuson-Moss Warranty Act, installing a replacement sway bar such as RC0020RZ-20 does not void your vehicle's manufacturer warranty, provided the installation is performed correctly and the part did not cause the claimed failure.
- Is RC0020RZ-20 legal for street use? Yes. SuperPro sway bars are designed and rated for street use. RC0020RZ-20 is a direct-replacement style bar that does not require any vehicle modifications beyond removing the OEM bar.
