GTSPEC's Lateral Link Arms are designed to lock out the existing toe angle adjuster and replace it with a stiffer adjustable steel arm with lock washers. The factory adjuster is prone to slippage under load and the soft rubber bushings are designed around reducing noise and vibration rather than providing maximum performance.
The GTSPEC arms are single point adjustable to reduce the chances of them coming loose during performance driving. GTSPEC's adjustable arms with their polyurethane bushings will aid in more consistent toe alignment during braking, cornering, and hard acceleration. These are best used in conjunction with the GTSPEC camber arms.
