Well now that I have had my 05 Z springs/Dspec setup for three months now it must have been settling further over the past two weeks. Starting only two weeks ago if I go over something pretty steep or go over an small depression in the road with my front left tire it causes a metal scrape sound.

At first I thought it was just my air diffuser that some of the clips had become loose. Well I got the car up on a lift and my drivers’ side cat has been making contact with the ground, which is the metal contact sound. Now it was not horrible but the other cat had nothing on it at all.

I want to mention that I previously had 03 Z springs/shocks on my car for a year and never had this problem going over the same bumps/roads. I took pictures with my cell phone when it was on the lift I will post up later.

 

did it really settle that much lower? check to see if you can weld an extra hanger to keep the cat sitting a little higher. there isn't much room but that is one solution to hlep it from scraping
