I am finally going to get new wheels. I am replacing Charcoal Bullet wheels on a 2002 gt with 2003 cobra wheels. The Bullet wheels have a 5.72" backspacing and are 8". The 2003 cobra wheels have 6.12" backspacing and are 10" wide. I am not sure how exactly the backspacing works and I need to know if this will cause a problem with the 2003 cobra svt wheels fitting on my car.
