Im just curious to what would be the best suited rear sway bar to be used with my Addco 150 (1-1/8")front bar? looking at either the addco 675 (7/8") or the 919 (3/4") any opinions is appreciated! thanks

btw, car in question is for my 71 scamp.

Hellwig 3/4", adjustable,dogbone style links. Just put one on my 69 B'cuda! Love it! Had a couple Q's during install and actually talked to a person who has done the installs!!! Phone was answered in 2 rings(no press 1 for english,etc) Excellent product AND customer support!! I believe Dave? hangs out over on FABO.

I have a 1 1/8" front and 7/8" rear Addco bars on my '69 Barracuda. Works great.

Call Addco or other mfgrs. for their recomendations.

Well the size is more your call. The bigger the bar more spring rate is added as the rear end corners. Essentially the rear bar is suppose to help understeer. But go too big and the rear end will want to come around on you if you are pushing it through corners. I would say a ¾" bar is plenty.

But then again, loose is fast!! You need to find out if you like a loose car or a tight car.
