I'm running 16x6 C2's with 205/55/16 rear and 195/50/16 in front. The ride is firm in the corners but it dosn't beat you to death all day so you can drive it without a kidney belt. I think the MaxxStrut uses a Rabbit strut cartrige that you can upgrade later if you want. My rear is lowered a little but still clears my Phat boy muffler, well most of the time it clears.
Mine is a 72 1302.
