Just had my D3 springs installed on my 07 STS-V after the install the car sat nice and low but after driving it approximately 3 miles away from the shop I noticed it started to feel a lil bouncy when going over bumps so I pulled over to get out and take a look and saw that the car raised itself again to the normal ride height so it's obvious that the shocks raised themselves back up how do I get the car to lower back again ???
