This kit is designed to be combined with a set of original E30 or E36 arms. For use with E46/Z4 applications, you must use E30/E36 original steel arms.
Using the same proven steering geometry and roll-center+bump-steer correction as the other SLR kits, the budget kit provides you with a billet steel control arm extension that is welded to your OEM control arm for over 100mm of track width increase which provides incredible steering angle (up to 65⁰ or more depending on wheel/tire combo).
E46 applications will require round delrin lollipop added.
