SuperPro Front Lower Inner Rearward Control Arm Caster Bushing Kit for Select Lexus 2006-2022 (SPF3692-90K)

Fits select 2006-2022 Lexus GS, IS, IS F, RC, and RC F models.

SuperPro Motorsport offset bushings are engineered to replace soft, worn factory rubber units, introducing additional positive caster into the front suspension geometry. This geometry correction provides sharper steering response, improved straight-line stability, and enhanced self-centering. By increasing caster, the vehicle benefits from dynamic camber gain during cornering, maximizing the tire's contact patch and preventing the tire from rolling onto the shoulder under heavy lateral loads.

Manufactured in Australia from a proprietary engineering-grade polyurethane formula, these bushings maintain OEM-level noise, vibration, and harshness (NVH) isolation while offering superior durability. Unlike rubber, this material is resistant to extreme temperatures, oils, and coolants, ensuring the suspension maintains its alignment settings under track or high-performance street use.
