This results in improved suspension geometry control, leading to better braking stability, sharper handling, and more precise steering feedback.
Designed for enthusiasts seeking peak performance, these bushings are essential for track days, spirited driving, or any situation where precise suspension control is paramount. The kit includes a pair of bushings, designed for direct installation onto OEM arms. Unlock the full potential of your Supra or Z4's suspension.
