These plates feature over 23mm of total camber adjustment (16mm negative/7.5mm positive), with the ability to make corrective caster changes to equalize side-to-side caster in the stock position.

Other features include replaceable waterproof German axial load bearings, and urethane bushings for long life, less deflection, and a smooth silent ride on either stock, or 2.5" racing springs.

Our camber plates are also engraved with the Ground Control logo in an arch which can be used to locate the plate in the stock position for easy, repeatable, adjustment from street to track and back.

All components are anodized or zinc plated for corrosion resistance.

We also offer our lifetime guaranty! (Bearings not included)
