Pro and Cons of a 1.25" Rear Swaybar

[Stg1Regal]

Been snooping around looking at front and rear sway bars...

Found a BIG rear one... 1.25" ... Could this be used in the Pro-touring arena or just drag racing?

If so what would be matched for a front swaybar.

Currently I have Grand National front and rear swaybars on my 82 Regal with poly busings in the arms front and rear.

Plan on stepping up the suspension to the better tubular designed trailing arms that do articulate on the rear, and up front, for the taller balljoints , correct uppers.

Just curious if I could use that rear swaybar.

ALso I will be stepping up to 17" tires and rims, wide as I can stuffed in all 4 corners.

thanks
