would -4.5 back spacing be pulled into the wheel wells to much, i have done a search on here and didn't come up with much, so if anyone knows what -4.5 back spacing looks like that would be great.

 

They would be pretty far inside the wheel wells. Seems to me stock wheels are about 4.5" backspacing so 16x8's would stick out about an inch farther than stock. I would try to stay around 3.75-4.00" backspacing with a 16x8.

 

ya, i believe you are right, i think stock is 4.5, so the stance would be the same ( besides 1/2 on more on the inside and out side)

Id personally go with 3.75-4.00 backspacing on aftermarket wheels... factory is too sucked into the wheel well and if you plan on running a wider tire you're gonna need more backspacing than stock to not rub or have issues at full lock
