Hotchkis Delta Caster/Camber Plates allow for more adjustment than stock mounts allowing for more alignment options. Hotchkis Delta plates feature polyurethane bushings for quiet operation and maximum performance and are CNC machined from 6061 heat treated aluminum. The TIG-welded strut hats increase strut travel which is especially important on lowered cars. Hotchkis Delta plates come complete with special strut boots bump stops hardware and instructions. Note: We do not recommend the use of Delta plates on coil-over equipped vehicles.
