i know theres guys that run the 15s but i THINK u have to do some grinding to your rear caliper to get them to fit.....im NOT positive on this but i know ive read that somwhere on here....its its true u may wanna go with 16s if u dont wanna take a grinder to your cal's

100% on the grinding to fit a 15" wheel on the back.
LOTS of grinding.

WHAT ABOUT THIS ONES WOULD THEY FIT?
WELD 96-58280 OR 90-58350
BOTH ARE:
15 X 8
BACKSPACING 5.50
OFFSET + 25.00 mm
I REALICE THAT I HAVE TO GRIND A LOT BUT THERE ITS NO 16 X 8 ON THE MARKET.THANKS

I think that is the right backspacing for the 15x8.

I know the 15x10 is 7.5" backspaced. And if I remember correctly, the 15x8 was also 2" smaller on the backspacing.

15x8 w/5.5 backspace is correct. Not sure on offset. I have the 15x8s.

backspacing and offset mean the same thing, but in different terms.

backspacing is measured in inches and it's how much inward of the total wheel width.

offset is measured in millimeters and is how much from the center point of a given width is is. positive inward from center. negative outward from center.

example:
15 x 8 wheel has a center point of 4". this would be 4" backspacing and 0mm offset.
