I'm going to purchase a set of rims for my 87 2wd. And I would like to know the factory backspace and off set. I'm getting 3.75 backspace and -19mm offset. How would these look?

 

The factory wheels are 7.5" wide with a 0 offset which would give them a 3.75" backspace. I think some of the factory wheels are 8" wide with a 0 offset which would give them a 4" backspace.

 

How would fender clearance look on a set of 15x8's with a +25mm offset and 5.48in back space

 

My concern on why I keep asking this is the factory 15x8 wheels I have fit the front fender great. Fills them almost that I could hold a straight edge and the wheels are less than 1/8th from it. But the back wheels are like 1-1.5 inch from them. And yes I know that the front wheels are wider apart than the back (slightly) but I'm going to purchase a set of American racing ar898 15x8 wheels but they come in 2 offset/Bp sizes. A 0offset/4.5 Bp and a 25offset/5.48 Bp. I want the wheels to "fill" the fender, but not stick out any. Or like less than 1/2inch. I don't really want to buy 2 different offsets for the front or back. But I would like to know how these sizes look in fender clearance before I buy. I recently purchased a set for a 06 f150 and thought I had the correct size and ended up them sticking out 2inches so this time for my 87 I'm going to do my homework before I buy. If someone has pics of wheels with those Bp and offset it would be greatly appreciated. Thanks in advance

 

Positive offset will make the wheels stick in a little more. Negative offset makes them stick out. So they would stick in a little more than the stock 15x8's. 1.48in more in fact

 

What about the 0offset and 4.5 Bp?

 

A 15x8 wheel with a 0 offset should have a 4" backspace but either way, the 0 offset should sit the same (or very close) to the stock 15x8s.
