Have these SPC camber arms on a 370z installed in the Rear for 20 x 11 rims they work excellent and got my camber in spec easily helping conserve on the tire wear greatly. Also the rubber bushings help keep the noise level nice and quiet for Daily Driving. The Voodoo 13 arms were terrible for the rear i tried them out on the car very loud clinging metal bearings the worst never again. stick with SPC you cant go wrong.
