Installation was easy. Springs seem of decent quality. Ride is firm but not overly bouncy like a low rider. Feels more like a sports car.

I installed these lowering springs on a '70 Chevelle. These springs are really short which worried me. The are a little loose in my opinion when you jack the vehicle up or raise it on a lift, but they seem just fine when the car is on the ground. The ride is a little stiffer in my opinion, but that is to be expected with lowering springs. If you are looking for a little softer ride I would look for something with a different spring rate.
