Torssion Bars

We are new to this game, we need new torssion bars for our 68 Barracuda. Ours are 13/16" diameter, we get quoted different diameters
is it worth upgrading? Would this cause any problems or other parts that would need changing. Are there inferior parts out there? We would be gratefull of any advice.

Depends what you use the car for.

Drag racers want the lightest spring rates on the front (smallest diameter) so that the front rises faster on the launch.

People like me that like to go around corners fast fit bigger bars for handling. Usually to make a car handle you need a bigger bar to match a heavier engine.

If you go too hard on the front spring rate the car will understeer and you will have to increase the spring rate at the rear. Usually this means fitting a rear sway bar if it has not got one or a bigger one if it does.

I had a link somewhere to a site about Mopar handling but it must be on one of the computers at work because i can't find it here?

This may help, I'm not the best one to give advice, but there is some interesting reading further down.
