I am looking into upgrading my .92" torsion bars on my 70 Challenger. 340/727,P245-60-15 & P275-60-15 tires, stock front sway bar & 3/4" rear, Viking DA shocks. Rear springs are the #3400043 (6 leafs) on both sides.
This is a street car and I plan on sticking with the 60 series tires which I assume will help absorb some of the stiffness of a larger torsion bar.
I am looking at the FF 1.06" or the 1.12" bars. I do not have any extra stiffening brackets and I don't want to add them unless needed. We have a lot of curves (round-a-bouts) and fairly smooth roads after the pot holes are filled each year
What do you suggest?
