Eibach Pro-Spacer System 16-17 Ford Focus RS 15mm Thickness

Spacers can only be used with wheels that have cut-outs (facing the hub) to clear the stock studs. Please check as follows: Original stud length (i.e. 35mm) minus spacer-thickness (i.e. 25mm) = 10mm excess stud length. The cut-out should have a depth of 11mm.
