help identify suspension
As far as the rears springs they're either 10" or 11" tall and normally either have a 175 lb.in. or 150lb.in. spring rates, unless when you order a kit you specify a different spring rate. I'm not sure who makes the rear coil springs for GC, but I do know Hypercoil makes some 5.5" ID pigtail 11" and 12" coil spring that you can use in the rear.
BTW, I use the GC kit in the front of my car, and all is good!
