OK so I'm gonna have to replace the sway bar on my wife's car (GS) It looks like i can get a good price on the GMPP front swaybar kit, but on one vendor's site, they do not reccomend using the front GMPP (34mm) bar without the GMPP rear bar.. i dont want to get the rear too. only replacing the front cuz it broke..... would it be a bad idea to replace only the front with the larger?
