I'm putting in the Eibachs right now and just finished taking out the passenger side. I noticed that the new springs are flat at one end while the stock ones are round. I know the flat part goes up but I'm wondering if I can reuse my rubber isolator with the new springs. It fits but since the old spring is round, the flat part of the new springs doesn't line up perfectly with the isolator. Can I still reuse these or will I run into problems with ride height? Noises? anything?

TIA

 

i think as long as they look good just re-use them..

but since oyur starting out with new springs you might a get the new isolators as well..

 

If you get new isolators from GM it's very likely that the rears will be thicker than the one's you have now thereby raising the back more than you might want.

There's a lot of posts about this from a few months ago might be worth a look.

 

Yeah i know the golden rule around here is to search first, but i've done that. didn't find anything that would help me. i'm just gonna reuse my old ones. but now i dunno how to get the damn spring back in. i took the arm out and tried jacking it up with the spring in place but after a while it was raising the whole car. this **** is turning out to be 10x worse than doing headers.

 

I put eibach srings on my car . I didn't want to use the old insulators , so i bought so big dia. shrink tubing and installed them around the top coils . No noise , sits a little lower .

 

On my install I purchase new ones for the front and reused the old ones for the rear. The new style for the rear are taller and will raise your car so keep your old ones.

I was very happy how mine turned out. My front ones looked kind of mangled when I took them out and I had no intention of pulling the front end apart again any time soon.

Buy the fronts ones new.... reuse the rears

 

thanks for replying but i finished the job already ended up reusing all 4 isolators. They looked like they were still in good condition. What i wanna try next though is removing them from the back and see if it lowers it more. IMO it could still go down by a hair. the front is perfect.

 

Yeah - I've heard that before - that they don't lower the back quite enough.

I don't know if I'd cut half a coil off the new rear springs myself but I've seen it done.

 

I agree the rear could still set a little lower. Get some rubber hose to cover the top coil so it is not metal on metal. This way you shouldn't get squeaks.

 

Try the heat shrink around the coils , The rubber hoes might be bulking to get around the coils . I what i like to do is take the shrink wrap , heat it up then apply another piece over it . So you more there for rubbing . I do this to $70k cars when they complain about noise going over speed bumps . Been doing it for over a year , no re-checks to date .

 

Thanks for the replies. i won't be removing them til after i take new pics of the car so other people who wanna buy springs can see how much they drop. right now i'm fixing up some minor cosmetic stuff. wanna make it look nice for the pics.
