For Sale: 2.5" ID Eibach and Hypercoil Springs. Some of these have never been used, most have been used once or twice. I tested a number of spring rates with my Cobalt. Many, if not most, coilovers or coilover kits use 2.5" ID springs. If you really want to change your spring rates, this is the way...

New: Eibachs cost $60.20 each = $120.40 per pair, Hypercoils cost $55.00 each = $110.00 per pair -- plus shipping to wherever you live (I'll provide shipping costs before you make a decision).

I'm selling pairs only.

Eibachs:
2ea 6" x 450 lbs @$80 for the pair
2ea 6" x 550 lbs @$80 for the pair

2ea 7" x 500 lbs @$80 for the pair
2ea 7" x 550 lbs @$80 for the pair

Hypercoils:
2ea 7" x 400 lbs @$70 for the pair
2ea 7" x 450 lbs @$70 for the pair

You can PM me if you're interested. I'll handle money exchanges via PayPal.

I'm using stance coil overs and would like stiffer springs for the rear. Will any of these work?

 

I'm pretty sure they'll all work. I don't know exactly how long the standard Stance springs are -- probably 7" or 8". I have Ground Control coilover kits -- they came with a 6" spring up front and 8" springs in the rear. I've been using 7" or 6" springs up front for a long time. I simply adjust the height to where I want it.

Here's what the Eibach springs look like for front and rear:



Here's the car on 6" fronts and 7" rears adjusted all the way down to the bottom:



and:



So I think either length would work. Your biggest challenge is figuring out how stiff you want. The photos above are on 650 lb rear springs and 700 lb front springs -- 10" wide rims and 255/35 x 18 Hoosier A6 slicks.

Are they still available?

 

Two pairs of Coilover Springs are sold - the rest in various sizes are still available (see below)!

IN ADDITION: I have two sets of Eibach ProKit Springs for Sale
1ea Set for an 05-10 Cobalt (front and rear springs) -- $185 plus shipping
1ea Set for an 03-08 Saturn Ion (front and rear springs) -- $185 plus shipping

These sell for $250-260 - according to Eibach they deliver the following drops:
Eibach Pro-Kit lowers the 2005-2010 Cobalt 1.6" Front, 1.8" Rear
Eibach Pro-Kit lowers the 2005-2010 Cobalt SS 0" Front, .5" Rear

The drops are about the same for an Ion/Redine. These are progressive springs, nice ride but stiffer when you need it.
