You are viewing Brand New Set of 30mm Roll Center Adapters designed by the inventors of the Drift Center Diff, Watanabe Service. The Watanabe Service 30mm Roll Center Adjusters are a must on any lowered Subaru (Impreza, Legacy, Forrester). When you lower your car you change the suspension geometry of your car as the lower arm angle changes. These will correct your roll center and allow you to have the original steering feel while having your car lowered.

*The set can be used with the OEM Lower Ball Joint as is and they are also available in 35mm.
