SuperPro 2008 Lexus IS F Base Fr Lower Inner Rearward Control Arm w/ Caster Bushing Kit (Motorsport)

Control arm bushings form the vital pivot and link between all core suspension components. SuperPro's 'offset' bushing options introduce additional positive caster into the front end suspension geometry. With a small but significant change the additional caster delivers several benefits: Improved straight-line stability and tracking; your vehicle will track straight and return to center with less driver input. Dynamic camber gain with steering angle “ the more your turn the wheel with additional caster the more both wheels will ˜camber' into the turn putting more of the tire's contact patch on the road as the suspension loads up in the corner and helping to resist the tire ˜rolling over' onto the shoulder and compromising grip. Enhanced steering weight and feel; the small caster change will weight up the steering slightly as you come off-center and the improved cornering grip delivers greater feel for the handling limit through the wheel. The caster offset bushings deliver only benefits with no negative impact on tire wear, comfort or unwanted handling behavior. SuperPro's polyurethane bushings are the culmination of nearly 5 decades of suspension expertise and development in Australia's harshest terrain. Designed with durability as a paramount feature we also bring ride and passenger comfort to the forefront of our development. Our designs and material compositions retain OEM levels of noise and harshness isolation while delivering superior performance and road manners in all conditions.

Upgrade front suspension response and steering feel with the SuperPro SPF3692-90K front lower inner rearward control arm bushing kit. Designed for select Lexus applications, this Motorsport caster-offset kit introduces additional positive caster into the front suspension geometry without compromising everyday ride comfort, tire wear, or predictable handling. It is a performance-focused replacement for factory rubber bushings and is engineered to improve vehicle stability, tracking, and cornering control.
SuperPro’s offset bushings help the vehicle track straight and return to center with less driver input, while the added caster promotes dynamic camber gain as steering angle increases. This helps place more of the tire contact patch on the road as the suspension loads during cornering and helps resist the tire rolling onto its shoulder. The result is enhanced steering weight, improved on-center feel, and greater feedback when approaching the handling limit.
Constructed from SuperPro’s proprietary engineering-grade polyurethane, the SPF3692-90K is designed to withstand extreme temperatures, oils, water, and coolant. The bushings are developed to retain OEM-level noise and harshness isolation while delivering greater durability and sharper suspension performance. Designed, engineered, and manufactured in Australia, this kit reflects SuperPro’s extensive suspension development experience and includes a lifetime warranty for added confidence.
