SuperPro 2001 Lexus GS300 Base Front Lower Radius Arm - w/ Caster Bushing Kit

If you're looking to improve your 2001-2005 Lexus GS300's handling, especially for straight-line stability and steering response, this SuperPro radius arm bushing kit is a solid option. These bushings are designed to introduce a small but notable amount of positive caster into your front suspension geometry. This change helps your vehicle track straighter on the highway, making it easier to maintain your lane with less driver input. It also helps the steering wheel return to center more readily after a turn.

Beyond straight-line tracking, the added caster offers dynamic benefits when cornering. As you turn, the wheels gain a bit more negative camber, which puts more of the tire's contact patch onto the road surface. This improved grip helps resist the tire rolling onto its shoulder in a hard corner, enhancing overall handling. You'll also notice a slight increase in steering weight as you come off-center, and the improved cornering grip translates to better feedback through the steering wheel, letting you feel the limits of the car more clearly. SuperPro has developed these polyurethane bushings with durability in mind, drawing on decades of experience in tough conditions, while also maintaining comfortable ride quality and OEM levels of noise isolation.
