On ground control coilovers how can you tell what the spring rates are

 

i read that you can customize your own spring rate...but not sure if that's true...(plz clear this quiestion up fo meh too)

 

i heard u can also. try asking the people that sells them, like the sponsors here

 

yes you can get custom ground controls. usually any performance/auto store that sells it has the option to do it

 

From what I've seen the regular springs that come w/ the GC Special Editions have a different numbering system than the ERS springs, so you can't go by that to tell the spring rate. The ERS springs have part numbers that reflect the spring's free length, diamter, and rate, i.e. 700.0250.0450 or something to that effect, means the spring is 7" long, 2.5" diameter and has a rate of 450 lb/in.

 

front=GC200.64.67
Rear=GC180.64.44

 

See what I mean, those numbers don't follow the normal Eibach Race Spring numbering system, so you can't tell the spring rates from that.
