Camber/caster adjustment plates engineered utilizing a unique, multi-adjustable design, these adjustable camber plates are an ideal solution. Works with any BMW-compatible front strut or coilover setup designed for original strut mount. Replaces original upper strut mount. Does not change front ride height. Crafted from aircraft quality aluminum, these precision machined adjusters feature OE style bearings and a bonded urethane insulator. The OE style bearing provides proper rotational compliance for the strut shaft and will not loosen or rattle like spherical-bearing designs. 100% urethane isolation prevents noise or vibration transmitted to car's interior unlike solid metal plates.
