I did a search already and couldn't come up with the answer needed. I have a set of ERS springs for my Ground-Control coilovers and don't know the spring rate. I purchased the limited edition kit.

What I need to know is how to read the numbers. For example, the rear springs thatcame with the kit have the markings as follows: GC180.64.44

Does this mean that the spring rate is 180?

Any help would be greatly appreciated.

whats the number on your other spring say. im wondering what the hell is "limited" about their limited edition kit. your spring rate is 250, pretty much what they offer as the rear spring rate for all non-custom kits.
and who is selling "limited edition" GC, i dont see it on GC website.

Thanks for the info. Their Limited Edition kits are for either 88-91 Civic/CRX or 92-00 Civic or 94-01 Integra. Their kits are labeled right in the Application Guide section.

I got the kit from Ground-Control two years ago. I got it on a dealer comp.for only $140. The only problem with the deal was I couldn't specify spring rates. I told them the vehicle was a '99 Si so maybe they put something together for me. I love the way the vehicle rides and handles, but at a couple auto-x's last year I thought it was a little softly sprung. I am getting more into auto-xing and wanted to start playing with spring combinations, or maybe get rid of the Tokico HP's in favor of some Illuminas.

 

Or some Koni's?

 

Tokico's and Koni's use different sleeves.

That is why I think I'll stick to the Tokico line. I have had good luck with my HP's but I think the dampening is too soft. They ride great for daily use, but I noticed that they weren't that great for auto-x. The car seemed to bounce a little more than on the street.

 

I have a set of GC200.64.58

I was told its a spring only sold to GC by Eibach. Its a semi-progresive. The rate on mine is about 380 on the top end.

 

im not so sure ground control offers progresive springs anymore. can someone show me a pic of a ERS that is obviously progressive?
