1-1/8 & 1-1/4 front sway bar vs factory 7/8?

Heres a little info on my suspension setup.

(Not sure if it matters) Car weight with me in it around 3400 lbs
V8 torsion bars
Lca stiffening plates fully welded
Weld in sub frame connectors
Hotchkis tuned fox shocks.
7/8 sway bar up front


So is a 1-1/8 pretty much standard?

Or would that be too stiff?

I went from the 205 to the 225. The car handles great, but it still feels like there is a slight bit of body roll, i dont plan on running a rear sway bar, would it hurt to go bigger in the front without there being a sway bar in the rear?

I know its not a auto cross car by any means but if i can stiffen the front up a bit id be completely happy, i mean the car drives good now but i like to tinker. Lol.
