Cam type adjusting kit designed for standard non-slotted 10mm hole struts. These allow for positive and negative camber change by replacing the factory upper strut bolt. Can be used to fine tune your suspension alignment after installing lowering springs or other upgrades. The head markings of the high tensile grade 12.9 bolts show where the cam is for maximum change and an easy-to-manipulate toothed washer lets you set positive or negative change. Full instructions included. One camber bolt required per wheel, sold as a pair (axle set).
