EZ Cam XRs camber bolts for the Scion FRS and Subaru BRZ are designed for non-slotted struts. They allow both positive and negative camber changes up to approximately plus or minus 1.75 degree by replacing the bottom O.E. 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.
