I ordered some Ground Control Coilovers off Ebay for my 2002 Maxima, but the auction did not list any information on the spring rates. I sent a message to the seller, but he obviously did not care enough to ever msg me back.

I have Ground Control 6055.01

On the springs are these numbers.
Front:
Eibach 159122
GC180.64.75
Rear:
Eibach 152017
GC150.64.66

I am not sure if this helps anyone in determining what the spring rate might be on these, but any help is appreciated.

Thanks.

 

I believe those are 500lbs/in front and 375lbs/in rear, but I could be wrong. Call Sportcompactonly.com at 888-766-0022. I'm p***ty sure they have this info.

 

Try looking up the part numbers on eibach's website or give them a call or email.
