I'm looking to replace my oem springs with some Eibach springs. I'm looking at the GC site but I'm not sure what size my original springs are.

I've found many posts stating the rates of oem springs but nothing about the actual dimensions of the springs.

Thanks for your help,
Brian

 

Wow, I'm suprised nobody knows. Maybe I'm not asking the question clearly?

I'm just looking at http://www.ground-control-store.com/produc...gory.php/CA=211

I'm waiting for my spring compression tool to come in and then I'll just try to measure them myself and go from there but I figured somebody must have been down this road already of ordering custom springs and not the typical kits available. So I was just hoping to get the springs ordered sooner than later.

 

The rates and lengths vary from model year to model year, but all OEM springs are nominally 4.25 in. outer diameter (so inner diam is ~3.25 in.).

Edit: That's actually at the perch (bottom end). The top-most coil (at the top hat) is slightly narrower, with i.d. about 3.0 in.

 

Thanks for the reply. I found the spring rates, but wasn't sure on other specs. So if the ID is say ~3.25, what does the 2.25 and 2.5 reference on the GC site? I thought these were also the inside diameter, but that sounds fairly small so I'm sure there a few things I still don't understand.
