Yes, there will be a difference. The rate of a .96 is 135 lbs/in and a 1.00 is 160 lbs/in For comparison, a .86 /6 E-body bar is 90 lbs/in and a .92 Hemi bar is 115 lbs/in. Is it worth the $159 to buy 1.00" t-bars? That's tough to tell. Quote:
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.

I have 1" in the 66 Coronet and find the spring rate perfect for aggressive driving with the heavy 440 up front. They probably would feel stiffer in your car because of the lighter weight of the small block. I would start with the .960 and invest in a set of Hotchkiss sway bars. You could always swap in the bigger bars later.

I was going to go with a big block, but I have everything for the crate engine to just drop in. I will be doing more street driving, but would love to have the better handeling if it's noticeable. Just want it done right the first time so I won't have to redo it later.

If you go to just suspensions website, they still have them for $159. I do not know if the shipping is still free though.

Negative, Ghost Rider. Shipping was 30.25 to Seattle area. At 159 bucks, I couldn't pass it up either...

The actual rate you get at the wheel from a torsion bar depends on how long your lower control arm is (B/E different to A) and how wide your wheels/tires are.
The longer the LCA and the wider the wheel, the lower the actual rating you get at the wheel.
Take that into account if you are trying to maintain a handling balance front to back.
In fact on the subject of balance, if you just fit stiffer front suspension without taking into consideration how stiff the rear is you will just end up with a car that understeers badly.
If you have understeer with a 0.96 bar you will make it worse going to a 1.00 bar.
If you have oversteer with the 0.96 you would be right to try a 1.00 bar.

The rates I posted where for E/B body length LCA's.
I thought changes in wheel offset effect the spring rate rather than width. The normal of the forces on the contact patch is the center which is also the center of the rim width.
I think these cars have so much roll in stock form, a large contribution to the understeer is due to tire losing geometry. Reduce the roll and let the much better modern tires grip in the front. In stock form these cars are balanced. They understeer greatly unless there is enough power to thottle oversteer.
I went to 1" front T-bar in an A-body (stiffer than a B/E) with just the stock front sway bar. But I had 225/60/15 tires. Car definitely increased it's cornering power. It still understeer at the limit, but the limit was raised.
I then added a rear sway bar with same stock front sway bar and same 1" T-bar. A little oversteer. Next I put on a 1 1/8 front sway bar. Seemed pretty balanced. Now I'm trying a 1 1/4 front sway bar. Seems to understeer. But now I've got old hard tires. I could play with my adjustable front shock too... On and on it goes...

I quite agree with you mate. Except that you have to consider the full length of the "lever" on the suspension. Which is the outer edge of the wheel.
I was just trying to keep it simple and thought it was worth mentioning because there are people out there that don't realise what effects they might end up causing.
A mate of mine with a small block fitted uprated springs and sway bar to the rear of his car and wondered why he was suddenly oversteering like crazy...

Would you guys recommend the 1" bar for my instance, still building the car. This is what I have.
69 B body, 526" RB stroker, pro street (tubbed with 4 link rear) real wide rear tires, want to use adjustable UCAs up front, otherwise pretty much stock components for front suspension. I will use a descent size front tire, say a 7" front rim (15" diamter). Obviously it wont be a G machine, more for fun and car shows. I dont think I will drag race it either. Too much expense and time to have it go into the wall, but I would like to run it to see what it would do.
Thanks,
Mark

Big bars = Big improvement.
