I have a 2015, 5sd Mirage. It's got about 28,xxx miles on it now. I saw the alignment threads and there is really good information on there about the rear alignment. I just want to share how 'bad' my alignment is. These pictures are with my 15 inch wheels; 15"x6.5", +38 offset. Tires are Falken Azenis RT615 P205-50-15. These tires do rub on harsh bumps.
Anyways, here are some pictures of my severe alignment. I'm checking on tire wear weekly. At the moment, I've switched back to the stock wheels/tire setup and yes, the rear tires are wearing out unevenly. Our roads in Minnesota are in constant construction and it's difficult to find a road that has been newly paved. I do need an alignment as the steering wheel is off a few degrees while going straight.
