I just got some Eibach spring coilovers and the front springs have this code:

1000.250.0.0450

Is the spring rate 450?


Thanks!

 

well I hope that I dont sound like a smart a$%, but the only real way to determine spring rate is to put them on a spring dyno/press. Check around, a local shop should have one if they are worth anything. I unfortunately, did not have the opprotunity to check mine before the install.
