yragat Well,I cut a little more off (little more than 1/2 coil) and its sitting pretty good now. Have room if they settle some and even if they don't it looks ok where it is. Been bouncing up & down on front and they seem like they are just right as far as stiffness
Thanks for all the input and advice!

ericnova72 At this point I agree with Rick, at worst you end up buying another set and starting again. You are kind of on your own here and will have to experiment to get the result you want.

If they are heavier it makes sense that they are going to have to be shorter in free height than the original Corvair spring to get you back into the ride height you are looking for.

Good luck, hopefully you get it on the first try

Rickracer Sounds like a plan, just don't be too disappointed if they wind up not being right, I've never had good luck cutting that much off a spring.

yragat The spring guru at Eaton said they will only settle about 1/2" over a short period and that's all

As for getting different springs--it took me 2 months just to find something that would fit and be a little stiffer than the stock corvair springs I knew they would be too tall The old ones were corvair HD and they are a
11 1/2" when new these were 14" I cut them to 12" I'm thinking maybe I should cut these to 11" they are heavier than my old ones and I liked the way it set before,just had one weak one--so had to change and didn't want to go with corvair springs because of frontend weight

ericnova72 I would REALLY advise you DON'T cut them again or you may end up buying another pair in 4-6 months. the ones you have now need some time with the weigth of the car on them and some bouncing up and down on the road to "settle in" to their final installed height. This is why a lot of people hate messing with springs.

After they have settled you can then determine if they need to be cut more, but it is still a trial and error(or is that trial BY error LOL)process, there is no formula that is going to give you the "miracle cut amount" to be perfect, you just have to sneak up on it 1/4 of a coil at a time.

Reassembled suspensions always sit high when freshly put back together, even with the original spring as the spring "relaxes" in the time it is out and free, still needs some road time to settle it back in. Also, any rubber bushed areas can't have the bolts tighten while the car is up in the air off the suspension or they will "pre-load" the suspension to set high. Don't fully tighten any suspension bushing hardware until the entire vehicle is reassembled and setting on the ground.

Rickracer I would say it's time for some different springs, ANY TIME you have to cut that much. Also, springs get stiffer the shorter they get, so it's not "linear".

yragat OK
I got the springs in--I cut 1 1/2 coils off and the darn thing is sitting like a gasser!!! got 3 1/2" maybe 4" of fender gap. Now what I want to know before I take them back out to cut more is this. Say that I want it 2" lower than it is should I measure how much 2" is on the springs while they are in the car in their compressed state and cut that much off??

yragat starting to put it back together now---have to wait & see
01-01-2010 11:34 AM
Rickracer I noticed that there was a mention of a shorter control arm? That WILL affect ride height with a given spring, maybe switch sides with the springs?

yragat Just want to give a big thumbs-up to amx180mph for his advice on the springs! checked with the "spring guru" expert at Eaton and he agreed totally that the ones that amx180mph recommended was the best match out of 800+ springs that they make !--but they want $159.00 at napa only $43.99. not trying to cheap out,but can't believe Eaton's are 3 times better???
12-23-2009 07:56 AM
yragat acording to the previous owner they were put on new 10 years ago
12-23-2009 03:04 AM
ericnova72 Yes, but they are fresh and don't have 40+ years of fatigue and one that is settled 1/2" more than the other.
12-22-2009 07:59 AM
yragat Yeh,but their heaviest springs only have a desighn load of 1258--thats what I have now

ericnova72 Have you tried Clark's Corvair Parts, or looked for any Corvair clubs online?? Clubs usually list links to parts services or have classifieds just like here at HR's.

I took a quick look at Clarks, they do list some in their catalog. www.corvair.com

yragat I don't know if I'm just dumb or what,but can't seem to understand formula's. And I've been getting all kind of conflicting advise
This is what Eaton told me

The HD Corvair spring has a rate of 188 lbs and the lightest M2 spring has a rate of 308 lbs. Cutting the M2 would increase the rate. So useing an M2 spring is not an option.

Now what realy causes you trouble is replacing the Corvair spring. I have looked over the specs of the nearly 600 coil part number we have and none of them even come close to what would work for you. We have not made any for yeas. And I do not know anyone who is making them. We have had some calling for them but not enough to justify making any. We need to make at least 50 springs to get the price affordable.

I told them it was not a corvair,but a 26 T with a 350/350 and thats what they came up with
