Review on ACDelco Professional 45H2124 Rear Coil Spring Set - Reliable Suspension Upgrade for Enhanced Performance by Aaron Ali

My Mazda 3 was doing all sorts of knocks and rattles in the rear, especially at low speeds around town. Eventually I discovered that one of the rear springs on the lower end of the forearm was broken so it couldn't be seen without disassembling the suspension. I ordered a pair of these springs and installed them in less than two hours. They fit perfectly! Because they are made from larger diameter billet, they are slightly stiffer than OEM parts; but they drive nice! Because the car is stiffer, it now rides about 15mm higher at the rear, but I don't mind that. This winter I will have some more snow clearing. I can recommend her unreservedly.
