Idk if this goes into appearance or suspension but I'm shooting for suspension. I think the front of the g6 looks awesome. I like the way it looks and the wheels and tires fill the fender well pretty nice up front, however, the back I do not like. The wheels kinda sink into the well and don't look good to me imo. I have wheel spacers on the rear end and they look nice but I also used a new electric impact wrench on my rear lug nuts only to find that a few of them ( my only evidence is the ONE that was messed up. explained later) had rust on the inside of the lug which caused one of them to fall off while I was driving, causing a "wub-wub" noise that scared the ish outta me. I get out my 4 socket iron lug wrench and test all 5 lugs and this one lug, with part of the stud inside still, just falls off with the mere pressure of my WRIST before I put my body weight into it. Needless to say I dont know how it stayed on while driving and I went as slow as possible back home after getting as many wheel studs as I could hold from autozone. Replaced the one that broke but now I'm just paranoid about it. I want the wider stance in the back (not flush but about 1 more whole inch per wheel. *2 inches in all*) but I want it SAFELY. Any recommendations? I am not trying to get a whole new axle though.
