can someone check the part number for me?

 

That's an Eibach part number, not a ground control. You don't have to worry about the spring, you need to worry about the shock and how it mounts to the LCA. But from what I have seen, a lot of manufacturers, send out EG shocks, since they have a wider mounting fork that an EK, and you just use washers on an EK to fill the space.

 

i know the spring doesn't matter. it's just better if i knew what spring rate it's for before buying.

 

Now see, you mentioned nothing about rates in your first post. Anyway, GC or Eiback should have a guide on thier sites, probably a PDF form.

 

yeah, my bad.

i checked both their sites but found nothing. that's why i posted on here to see if anyone knows. i must be blind.

 

"How do I tell what my spring rates are?

Ground Control sells Eibach Race Springs (ERS) which are labelled by 3 different values in the following convention: length . diameter . spring rate. However, ERS will come labelled in either Metric (mm.mm.N/m) or English (inchx100.inchx100.lbs/inch) units. 180.64.61 is the same thing as 700.250.350. The conversion from Metric to English is (/.254, /.254, x5.7) "/" means "divide by", "x" means "multiply by". "

So it looks like you have a 700mm long spring, 250mm in diameter with a spring rate of 360lb/in.

That info was taken from HERE.
