Offsets

[98bimmer]

Hey, whts the offset of our cars?

[mookish]

Front: +13 - +15
Rear: +20 - +25

Somewhere in that neighborhood. (staggered setup)

Im running +15 at all four corners and do not have an issue.

I saw some rims...but the offset is 40.

Most stock non-staggered wheels are 20mm offset.

That is too high for your car and any BMW 5/6/7/8/Z8 models...they all have an offset range between 11mm-28mm (with the latest 5/6/7 having a few staggered rear wheels with offset as high as 32mm)

The BMW 3/Z3/Z4/X3/X5 have a wheel offset range between 35mm-48mm...so that 40mm wheel offset wheel you're looking at would work fine with any those models...but not yours...unless you purchase wheel spacers, too.

Thank you very much. :)

proper offset range depends on the width of the wheels.
You could run 8.5", 9" wheels all around and have around +15mm-20mm offset
