Old Man,
Thanks for the wordy reply. Far from an expert on physics, I admit readily. Do know that when I use the hand brake in conjunction with the brake pedal in panic stops, it feels sooooo much better :laugh3:
I've been running these Stockton solid steel rims I had made up a few years ago, went to 8" for the 31x10.5's. Very noticably heavier than the five spoke Jeep alloys that came with the Classic I bought new in '98. But had planned to do more 'wheelin than I really do, figured I had to go to 4.5 bs to do this.
Never replaced the 3.55's, though I have 4.10's and tads that have been sitting in the garage for about three years. Unless I'm blessed with another dd, the gears probably will never get in.
Mileage has always been dismal, with gas what it is, figured that the aluminums' in the attic would make a significant difference.
The deciding factor that popped this idea in my head is that I'm closing on a getaway house in fl. in dec., and being that I'm flying-phobic, will have to use the xj to make the trips up and down from LI, NY (plus to get around Orlando, duh). Really won't be 'wheelin as much as I planned, so tire/rim/bs/ww stuffing is not really an issue anymore.
If you say don't bother, I'm sold...
Thanks again, all other replies too, much appreciated...
Mike
