I just wanted to get clarification on this one. I was told once before that you can not put 15's on a '05 because of the rotor size and the brake components as well. The other thing is the way that the wheel sits when mounted.
I looked a couple of aftermarket wheel makers and no one has anything available in a 15" rim.
15 will NOT work on an 05, I believe tireack clearified that last week. As for the mounting problem, I just test fitted a steelie and it WORKED! I will post pic here in a sec.
