yeah I'm thinking the springs are shorter than the RS springs. The RS springs are the same height as the FRPP kit springs, but the RS springs feel a bit stiffer.
I think I'm going to order the GAZ kit from BAT Inc. I looked at the Spax kit and have done some research on it. Some people have said that making height adjustments is a pain in the nutz.
