The original affordable solution to add rear grip to a z33/z34! This adapter relocates the factory Nissan rear toe arm location to eliminate the toe out on squat. Rather, this kit changes the suspension geometry to toe in on compression, for an increase in traction while drifting! This adapter allows you to run multiple toe curves from stock up to 1" of toe gain, eliminating the need for an excessive amount of static rear toe in. Includes new shorter rear toe arms, eccentric lock out washers and necessary mounting hardware. Made in the USA! For use with factory nissan/infinity rear knuckle. Worn or cracked bushings in the knuckle will result in premature failure and should be replaced prior to install. If installing on a car with a sandwich style dual caliper bracket longer bolts will be required to replace factory studs.
