Lower control arm parallel to ground - alignment problems?

I have 17's on my '72 with the same tires, have tried that torsion bar and stock. It's going to ride rough, Bilstein shocks. Doesn't drive well either, always have to drive it. I will say that I haven't experimented with getting the numbers on front end alignment. Been too busy. I like the look of 17's, but ride rough, no side wall.

Sounds like your expectations of "rides nice" are different than mine. I love how mine rides, about the same as my Challenger R/T did and (I expect) any newer Mustang GT. Not knocking your opinion.

In regards to your "always have to drive it" comment, I have an issue with mine where I was only able to get +1 degree of caster on the right and settled for that on both until I get it figured out. So I too have to drive mine when it is a little bumpy or rutted. But I am certain that with more caster it will drive great. Is it possible that your wheels/tires/TB/shocks have nothing to do with how it drives and it is more that you have an alignment that is causing your issue?
