On my T/A, I run the 1.24 TBs and 225 pound/inch with 5" free arch rear leafs (fiberglass mono-leafs from FlexaForm)... compressed to about 1.5" remaining arch,... and have 1.25" solid fron sway bar, 1.0" solid rear sway bar, Red re-valved Konis front/rear... car handles great, very neutral; weight is ~3150 w/o driver and with ~1/8 tank of gas (52% front, 48% rear)... this data is when the car is setup for national SCCA E/SP competition. even on the hi-speed road courses it handles great.. still relatively neutral.

I think the weight% with the 426 Hemi up front is going to be greater than what is indicated...??? I'd use a 1.0" rear sway bar to help offset the front weight.
