The only rub I get is at full flex on the trailing edge of he front fenders. My rear doesn't flex enough to really stuff the tires, but I get some slight rub on the inside lip. I have already trimmed one rear, and it took care of the rub. I get some rub on the control arms at full lock, and I need to adjust the stops out a bit.
The rear springs are from a 93 4-door that was in very good shape, with no sag. I added the Triangle add-a-leaf that I had laying around, no ideas on the specs, but its full length, and a bit stiff.
The fronts are also from the same 4-door, and also had no sag. I have not yet hacked the front, but am going to do some pretty liberal trimming on the fronts. As soon as these 32s are done, the Jeep will get 33s, and an 8.8 rear with 4.88s. I already have the 8.8 sitting here, and a non-disco front Dana 30 with the 297X joints out of the above mentioned 93.
