I'm getting my 94 z28 ready for auto-x, and I need to find out some info about springs. The car has to stay at stock ride height. It cannot be lowered.

Are 94 Z28 springs the same as SS springs? My Z28 springs are 13 years old, and I imagine they are pretty worn out. Would I gain any handling advantage by switching to newer Z28 or SS springs?

Just because spings are 13 years old does not mean they are worn out. If they are not sagging, then they are fine.

What year of SS are you talking about also? Some years got 1LE springs and others didn't.

They aren't sagging. The car sits at normal height. You think they are alright even though they are old? If I do upgrade, I should look for 1LE springs instead of SS?

Or go for some strano springs he swears by them as well as all others the auto-cross

If they're not sagging they are fine. If you want more rate at the stock height (or a little taller), get 1LE. Some SS's had the same springs that Z28's got, and some SS's and Z28 had 1LE springs.

If you want to lower there are other alternatives.

where do I find 1LE springs. Can I only get them through other members or is there a shop that sells them?

Greed4Speed

They were GM, so you have to find used ones. I haven't seen any for sale in a while.

I can imagine they are a valuable comodity.

I'll just put some spring helpers in my stock springs and call it good.

What kind of shocks are you running? If you are running stocker decarbons then I would worry about those well before springs.

I bought a set of bilstien HD shocks, and I'm really thinking about getting summit lowering springs.

The bilsteins valving isnt meant for lowering springs if you want to run those shocks either stick with stock springs, talk to sam strano about revalved hds (but hes out of stock and will be for a while), or go for some adjustable konis.

I thought you wanted to run the car in F Stock?

You can't run aftermarket springs in Stock. You can't even run alternate factory springs unless you convert the entire car to the option package with which those springs were available.

In theory you could convert the car to 1LE specs so you could run 1LE springs. The entire car would have to converted to a 1LE to be legal however.

Frankly, that seems like a lot of money and work for little benefit since the 1LEs have only slightly stiffer (360 vs 292) front springs.

I changed my plans a little bit. I'm gonna run STU the first year, then get some good tires and run ESP the following year.
