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

Not suitable. Although they are the same length, the final wrap on both ends is narrower (pigtail) than the OEM and does not seat properly. You can't even install a rubber grommet. Many people have mentioned that the car is about 1 inch taller with them. That's why it raises the car over IMO because it can't sit properly in the control arm or body. If you look at the last picture you can see the difference. Mazda 3 2012.
