15mm-26mm depending on the width of the wheel.
Yes, it was patently obvious that you put that stipulation, but then you set a (potentially) confusing limit based on offset alone without specifying the width causing the condition.
Well, sure. It's beholden upon the guy asking the question to verify his fitment, and there are approximately 4 million resources posted around this site that will allow him to do so. I picked that number because the very very commonly available E38 wheels that are 8" wide have that offset, and (detail I left out) will NOT rub the strut with any tire narrower than 225s. 225s will almost always rub. Anyway, within the most common E28 fitment wheels which tend to be 7-8" wide, 15-17" in diameter, and fitted with 205-225 mm tires, the et 23 is your safe practical upper limit for the front (will work with the right tires), and et18 your safe practical lower limit for the back.
But now I've spent time typing this stuff up, which I was hoping to avoid by my vagueness in the first place. Argh. Since I've done that, I might as well go ahead and inform the OP that spacers can be used to bring the effective offset down, but wheels that are too low in offset can't easily be adapted to fit--you have to modify the body of the car. There, more useful info.
