Which Torsion Bar?

TTBF is finally starting to slowly subside = (Torsion bar thickness fear). I have the 1.03" Firm Feel bars on my '68 convertible with a pair of '68 right side Super Stock springs in the rear. I did have to use 1" lowering blocks on the rear springs to get my stance acceptable to me. The spring rates are perfect for the open road, daily driving and spirited handling. They also hook up excellent on hard acceleration with the help of properly adjusted slapper bars.

With the modifications I've made on my '68 and the fact that it's a convertible, it tips the scales at 3700lbs without me in it. That's up there. I could use an even bigger front torsion bars and still be happy with the plushness of the ride. I do run quality Koni shocks on the car. On a lighter car, I would say the 1.03" bars are big enough.

I don't run my cars down in the weeds like a lot of people seem to do these days, because I drive my cars over the open roads here in California and Nevada. I do take the old highways and roads less travelled as often as I can. They can tear apart a lowered car in short order. I have even bottomed out on several occasions at speed in both my '68 A-Body and in my buddies '69 B-Body. Fortunately, nothing that couldn't be fixed at home in an hour or two was damaged, but we were 8+ hours from home and the cars remained drivable until repairs could be made after the trip.

The B-Body had the factory bars in it, but it was set-up at a practical, real-world, over-the-open-road survivable ride height like my A-Body. They are still way too soft of a spring for the car. He could easily use the 1+ inch bars in that big block car.
