I have a set of new Mopar Performance .960 diam torsion bar and was wondering if it's worth stepping up the the Just Suspension 1.00 in diam bars they have advertised. I am into agressive street driving and would mind doing some other events that include some nice twist and turns.

Here is the info:

1970 challenger
360 5.9 crate engine
automatic 727 low stall speed
magnum force tubular/adjustable control arms and dropped spindles
Firm feel stage two ps box fast ratio arm
kyb shocks
stock weight in frontend
still out on tires and wheels, probably start off with 15x7 steel rims on cooper cobras
larget tie rods and solid sleeves
still out on disc brakes
subframe connectors
rear suspension is still up to debate


what would you suggest?
