I have a 96 z28 with worn out original shocks (105K miles) and the passenger side is about an inch lower than the driver side which is fairly normal. My question is how much of this sag could due to the worn out shocks vs. my springs. I am going to replace the shocks with some SLP take off decarbons and I have a set of rear WS6 springs but I'm worried that the rear springs may be a little too stiff for the shocks. However, I don't want to have the sag on the passenger side either. I know I can try to switch the springs from one side to the other too and maybe that is the solution. Any help would be appreciated.

 

I just did front springs in a post above. My problem was sagging front, not rear. I don't think the shocks contribute to lift. Sag is likely all springs. It isn't unusual to see people cut a little off one spring to even things out if there is a discrepancy.

 

It could be a wore rubber isolator (big rubber o-ring)on top of the spring..Or your missing it...

 

You could remove the driver side rubber isolator block and put heater hose around the end of the spring to cushion instead and maybe even it up that way.

 

Thanks for the insights. The height difference is 1/2 inch in the rear and a quarter inch in the front so I am thinking about swapping springs in the rear from one side to the other and hopefully that will get it balanced out better. I have another set of springs also but they are the stiffer WS6 ones and I'm not sure how well they will match the stock shocks.

 

Depending on the year of your car and the year of the WS6 springs, they may be the same. My '95 TA non-WS6 car has the same exact rear springs as my '99 WS6 TA, same part number tag was on the springs.

I later got 1LE rears for the 95 and it made no difference in ride height but did stiffen it up a tad....I think all f-bods ride lop sided after a little bit of time, both of mine are 1/2" off, the 95 with 100k miles and the 99 with only 24k miles....although the 99 sits a full 1" higher on both sides than the 95....with the same exact springs.

 

The WS6 springs are off of a 97 WS6. They had 12000 miles on them when removed. I believe they are rated at 130 - 170 lbs vs 114 for the stock springs. The list of mods I'm doing right now are new J&M rear lower control arms, new J&M panhard bar, new Moog bushings and endlinks for the stock rear sway bar, 1LE front sway bar with new Moog bushings and endlinks and new stock shocks if that makes any difference. I realize the stock shocks don't have the best valving but they are a cheap band aid for now as I have a few other parts of the car to fix up. I don't think the increase in the WS6 spring rate is all that much and hopefully it wouldn't severly affect the ability of the shocks to work correctly.

 

I can relate to your problem,mine are the exact same way.and for future reference shocks have absolutly nothing to do with ride height,only the springs determine the ride height.let me know what works for you.

 

I think if I can carve out some time this week, I'll swap the shocks out and switch the springs from one side to the other and put my new panhard bar on. I'll let you know how it turns out. My rear end is also a little out of square (less than a half inch) so I'm hoping the new phb will fix that.
