Toe - Another tire wear issue and an under valued performance tuning resource. Proper toe adjustment can transform turn-in from "limp" to "alive". Whitelines unique toe lock kit will lock the toe into place, for precise tuning of the suspension using Whitelines adjustable arms. The KCA377 toe-adjuster locking kit is designed to complement cars already fitted with KTA107, KTA108 and KTA109 camber & toe adjustable control arms . This kit replaces the stock toe-adjuster and locks toe in place, eliminating the tendency of the factory adjuster to move and alter the required toe settings. This is particularly relevant for race or rally vehicles or other high load applications.
