Planning to get some wheel spacers for my 2011 328i xDrive LCI E91, just looking for some advice on what wheel spacer size(s) to get for some new wheels.

The pictures are with 17x8 ET34 style 284 wheels with 225/45-17 tires, but I need spacers as I’ve got a set of 18x8 ET45 wheels (with 225/40-18 tires) that will sit in further than I’d like (so I’ll just add 10mm to the following measurements for the spacers).

Am I right to assume the measurements should be to the inside of the wheel well, where the fender is? From what I can tell, the front need about 10mm and the back 0mm (???), which is quite odd as the back isn’t flush. Just for reference, the 30cm mark on the ruler lines up with the edge I put against the wheel and tire.

I don’t need the flushest fitment possible and prefer ease of fitment/no rubbing over aesthetics, figured I’d push them out a little as I would need to get 10mm spacers anyways due to the new wheels’ ET, so I might as well get larger spacers at the same time for a better look, just wondering what that larger spacer size should be.

Any thoughts?

It appears to me that 10mm on all four corners will make them more flush and give you room for the suspension to flex during spirited driving.

By going from a 34 to 45 offset, aren't you already pushing the wheels out 11mm?

I'd recommend that you, first, install the new setup and then check for clearance before ordering parts.

No, you've got it backwards.

Sorry, you're correct.
