Like the title says, I'm looking for a 2.5ID 6" 350lb coilover spring. 7" QA1s won't let me get where I'd like to be without unloading the spring at full droop, which I understand isn't fatal, but I'd prefer not to do. As far as I can tell, most manufacturers (QA1, Eibach, Hyperco) don't make 6"s in rates lower than 450 or so.

I do see that Swift makes a 65mm ID 6" 336lb(6kg/mm) spring - I assume there wouldn't be any reason not to use this with a 2.5" collar? However, please let me know if any other manufacturer has a suitable spring. And if there's an online retailer that carries Swift at a decent price, I'm all ears. Thanks!

 

If a 7'' spring will unload at full droop, I don't see why you would want a 6'' spring. That would make the problem worse.

With my 7'' rear 350lb QA1 and a 11.5'' rear ride height the spring did not unload. However I am running ISC top hats.

You should buy my springs.

 

eibach certainly does make 6" long 2.5 springs down to 200 lbs. truechoice and ground control both carry the full line.

 

I have the same rear springs and tophats and the lowest I can go is around 13", just eyeballing it. I don't want to go a lot lower, but the shorter spring would put my range of adjustability lower. Unless I'm really missing something.

I'm not finding the springs on either website, but I'll give them a call Monday. Thanks.

 

GC's web site doesn't seem to list them.

I've owned a 6" 2.5 375 lb/in Eibach spring in the past, though -- that's the front spring for the standard GC Miata coilovers.

I still don't understand what you want to do though? If I'm understanding you right, shouldn't you want to go to an 8'' spring and just use the perch at a lower point on the sleeve?

 

H&R. I ordered my 2.5" 400lb 6" springs here: http://store.allsprings.com/25-id-ra...ngs-p1846.aspx

 

I may have some id be willing to part with, but I have to check, pm me if you are interested

 

nah, you'd have to get the 2.25"

Still should fit, Splittime uses 2.25 springs over his bilstiens.

 

I thought hyperco did. You could probably pick up a cheap set of $50 coilovers on ebay for whatever car, and find something with those specs
