uberwgn, are you trying to lower your car, return the car to its original height or what? Since your car now has H&R springs I assume the car has been lowered. Why the change to Eibach springs? Like Gilly says, the manual has a point system that is used with stock springs (which also are color coded based on variations in length) to determine what pad thickness is needed to attain the normal, design ride height. When aftermarket sport springs are used, it is a crap shoot as to how thick the pads should be to deliver the desired ride height (which in any event will be lower than stock). If you want a slammed look with probable tire/wheelwell interference at the front and a great deal of negative camber at the front and rear, go with thin pads. With my 124 wagon I used Eibach springs and went with the thickest pads available and the car is still lowered by about 1" from stock with camber at the front at approx -1.2 degrees and the rear (without an adjustable camber link) at -2.5 degrees. I had to buy an adjustable camber link for the rear to get the camber to an acceptable level for the street. My 210 wagon with H&R springs and the thickest pads available has -1 degree camber front and -1.5 degree negative camber rear. The 210 is really at the limit for acceptable street tire wear. It all depends on what you are after. Mark
