I found a set of gc coilovers for sale and asked the guy what the spring rates were and this is what he responded with :
41/99 0600.250.1000 & 31489 0800.250.0500
I don't know what the spring rates are with these numbers. Any help? Thanks

 

if it follows standard GC markings they should be as follows
0600.250.1000 = 6" spring , 2.5 diam , 1000 lb
0800.250.0500 = 8" spring , 2.5 diam , 500 lb

BUT I have seen some OTS coilovers from GC that had retarded markings on them , when you get the ERS springs from GC they have standard markings on them that you can actually make sense of...

 

[edit] well, nevermind....

0600.250.1000:
6" length
2.5" inside diameter
1000 lb/in

0800.250.0500:
8" length
2.5" inside diameter
500 lb/in

I think I have the ERS springs. How can I find out those spring rates?

look on the spring, there should be a painted label. if the label does not conform to the above method, then its a vehicle specific kit and the number identifies the car it is made for, not exactly the spring rate.

ah , that makes sense.
