I have a 1995 9C1. This past weekend, my friends and I installed the Stock Impala ss springs and a new set of shocks on the rear axle and it dropped it about an inch. Fine.
Yesterday I had a reputable shop do the same thing to the front (We couldn't do it because it is a Maine car and the shocks had rusted to the frame...the old shocks broke during removal). Only this time it RAISED the front end. As in the Impala SS springs make the car sit HIGHER that it did with the 9C1 springs! WTF?

My car has about 175k miles on it and most likely, the old springs/shocks were original equipment. The new springs were out of a SS with +/- 75k miles. The new shocks are, well, new. I can stick six (6) fingers vertically between the top of the front tire and the top part of the wheel opening, I want 1-2.

Will it settle down? Should I cut my 9C1 springs and re-install them? The car doesn't feel as secure in the corners as it used to, though the new shocks are great with bumps and RR track crossings.

Any comments or suggestions?

First question is--are you sure that the springs actually came from an Impala SS, and they were the original springs--was there still a factory ID tag on the spring(s), and what does it say?

Second would be an observation--the springs may not be properly indexed back into the pocket on the frame or in the lower control arm--there are 2 holes in the arm where the spring rides, and they are used to check the position of the spring--one hole should be covered by the spring and the other should be clear--it also acts as a drain hole for the spring pocket.

What shocks did you use? I am not necessarily thinking that the new shocks may be "holding up" the front end, but it may take a little time to let the front end settle, between the spring and the shock. Your description sounds like some other problem, however.

Let us know what you find out!

In addition to Bill's excellent recommendations...

It's possible that this shop torqued back the control arm bushings with the suspension "hanging". The proper way to do it is with the weight of the car on the suspension (i.e. at "ride height") to avoid binding the bushings and causing this problem.

Just another possibility to add to Ed’s & Bill's suggestions - the shop may never have loosened the control arm bushings (a common short cut). In this case the front end my settle in time - with the attendant damage to the control arm bushings as mentioned in Ed's post.
