They dont clear the front brakes on my e30 bmw.
So you have steel spacers then? where'd you get them?
haha, no i've got some cheep-o aluminum from pepboys, I suppose you could break one of you lug stud things, or worse fuck the treads in your hub if you had big enough spacers in there that expanded to much over the expansion of the steel, but i don't know, i really don't see that, but i don't know.

:bigthumbu
your really probably looking at this because of that extra 1/4"^^
when i measured the 15x10 it came to just over 11" ( I think it was 11.25") with both flanges,
so we'll call it 11" and we'll call the 15x8 at 9" over all.
we need to start from the center of the wheel since thats where the offset is measured from,
so the over all width divided by 2 will get us there, 9"/2=4.5" ,
4.5" back space would be on center or 0 offset,
but your offsetting from the center of the wheel by 2" with a 2.5 inch back space,
so 4.5"-2.5"=2" , your 2" offset is towards the back of the wheel so its negative and there are about 25.35mm in an inch,
-2" * (25.35mm/1") = -50.7mm would be the ofset of the wheel
the best way to order properly, take off a rear wheel, jack the car level from end of the suspension its compressed as if it where on the ground with a wheel, measure the distance from the wheel mounting surface in the direction parallel with the studs out to where you would be even with the edge of the fender. if you have say 7" then you want a 4" back space on your 15x10 that has actuall width of 11", the "front space" is 7", so the back space is 4". now repeat up front.
that works perfectly if you run 0 degrees camber,
if you have camber; when your tire leans in from camber you can make a right triange(vertical line up from bottom edge of tire, bottom to top edge of tire, and top edge of tire back to your vertical line) and take half that top side out of the back space, if half that top line is 1/2", your back space would need to go from 4.5" to 4" to be flush at camber.
holly shit, some body go order some wheels
found it wedged down in the power steering lines. The drive line gremlins were way worse than the dumb ass gremlins that day, swapping engine trans :ugh: and diff this weekend. This car has been through a lot but still has lots of fun left in it!
