Product Details

If you're looking to improve your vehicle's straight-line stability and cornering performance, this offset bushing kit from SuperPro is a solid option. It's designed to replace the rear bushings in your front lower control arms, introducing a small but significant amount of positive caster into the suspension geometry. This change helps your car track straighter on the highway and makes the steering feel more substantial as you come off-center. In corners, the added caster helps the tires maintain better grip by adjusting camber dynamically, reducing the chance of the tire rolling over onto its shoulder.

SuperPro has been developing suspension components in Australia for nearly 50 years, and they've put that experience into this kit. They use a proprietary engineering-grade polyurethane that's built to last, resisting extreme temperatures, oils, and water. Unlike stock rubber bushings, this polyurethane material offers improved performance without sacrificing ride comfort or introducing extra noise. This kit is designed to fit a range of Lexus vehicles, including models like the GS350, IS250, and RC350, offering a noticeable improvement in handling feel and stability.
