Maximum Offset? 90 535i? ET30 okay? or No?

I'm running 18" with a 15ET. Would 5mm be considered a drastic change?

Well, unless I'm calculating offset backwards, your 15 mm ET + 5 mm = 23 mm offset, which is exactly what the early E34 came from the factory with. So, unless your tire sidewalls bulge out too much and rub on the spring perchs, you should be good to go.

But, triple-check with with folks more knowledgeable on this topic than I.

I messed up: MEANT to say 15 mm ET + 5 mm = 20 mm offset, which is exactly what early E34 came with.

Still, it may be the spring perch clearance that makes or breaks a given wheel/tire combination. Triple check.

no.. no... sorry... my wheels have a 15mm offset. Which is 5mm off what the E34 recommends at 20mm. So I was wondering if the 5mm difference is considered drastic. Sorry for the confusion.
