what size wheel spacers needed?

[bb525i]

i have recently been given some 18x8 and 18x9 1/2 wheels for my 94 525i. i tried putting them on today and the 18x9 1/2 won't fit on the back due to the rim hitting the lower control arm. my question is what size spacer is needed to clear the lower control arm. thanks for the help

Throw the rim back on, see what the gap is from proper fitmet to the wheel hitting. Then add 5 mm.

The wheel is hitting the control arm before it gets anywhere near the the hub. Not sure how i would be able to get measurement if i cant get it on. Any suggestions are appreiciated

I run 18x8.5" wheels in the back with no issues at at all. Your probably gonna need a 1/2" spacer at the very least. With that big a spacer you should get a wheel stud kit. The last time I saw a 9.5" wheel was on an E39.

I have a stupid question but its because i dont know. The numbers on the back of the wheel next to the "et" is that the offset? If so. The rear are 45 and the fronts are 35. So would a half inch spacer be enough for cleareance. And should i also get the same spacers for the front

Yes the numbers next to et are the offset. Et is just another way of saying offset. Me personally I would go with a 15 mm spacer. This will give u plenty of clearance while adding a more aggressive stance/ profile to your bmw.

What is 15mm in inches? Half inch or a full inch?

[Ivan413]

6/10 of an inch or 6cm which is a little bigger than .5 inch which is about 12mm
