Ok, My brother and I got into a debate about our DSM's. Quick back ground is- Our father thought he would be nice and while we were on vacation install his Eibach and Illuminas for him (mine are already installed). Our kits are the same except his car sits about an inch lower than mine. Upon further investigation, dear ole dad forgot to put the bumper stops in. I said that, that is why his car sits lower and that those are needed. He says other wise.

 

bumper stops???

you talking about the rubber piece that sits on top of the spring? that would be a bad idea if you forgot that but I dont think anything else would cause a lower height, unless one has sportlines and the other has pro kit

 

The 4 yellow rubber pieces. Called Strut Bumper.

that will give him a pretty bad ride and its not to good for the struts as well

 

i stil think you guys must have diff springs. that piece needs to be instaled but doesnt change ride height
