Maybe someone has some laying around?
looking for 2.5 by 7 maybe 6. rates between 250 and 400.
Ebay sleeves too!

 

6" will be too short for 250 or even 400. you need be running 550+ for something that short.

I don't have any extras, but you can buy springs from trackspeed engineering, summit racing, and this site:

As for the sleeves, yea you will probably have to ebay that. I don't know anyone who makes sleeves for us other than the ground control kit and that comes with springs already. (which might not be a bad alternative)

 

I mean the ground control sleeves aren't that nice. Some of the Ebay kits come with two locking rings. The springs are 2.5 by 7 Eibach springs. Why don't I just use 400 or 350 and 250 QA1 racing springs they should be. How can springs be different?

 

How much you trying to pay for sleeves?

 

I just think at 250 and 6" spring you would be too short and getting on the bumpstops. try it though and let me know!

 

Let me check my garage. I know I have a few sleeves, but they may have been trimmed to fit the Illuminas. I also have some springs, see below. They're yours for the cost of shipping, if you're interested. Also, I can snap pictures if I can locate them in the garage. Springs are just over what's the recommended maximum for the Illuminas, and too tall for them as well.

Wire diameter: .485 in.
Coil Diameter (center to center): 2.995 in.
Number of coils (free/active): 6.5 / 4.5
Spring length: 7.3 in.
Calculated spring rate: 465 lb/in

 

I don't think these the right diameter. Do you think they will fit bilstiens? also 465 is a lot. But regardless thank you.

 

i have 7" 420lb 2.5ID ksport springs i took off coilovers a few months ago that ill sell cheap.

 

I ended up going with 2.5 by 7 400/275

 

I think I should have gone with 6" springs. With the springs cranked all the way down I'm having trouble getting under 13" but to get any lower I need some ISC top hats as well.
