The new EZ Cam XR is designed by SPC Performance for non-slotted struts. It allows both positive and negative camber changes to your MR2 Spyder, MR-S, Roadster (ZZW30), by replacing the upper OE strut/spindle bolt. This easy to use adjuster provides built-in adjustment over the life of a vehicle just by rotating the head of the bolt. Each kit contains two cam bolt assemblies, enough for both sides of the vehicle.
