Yea it's the distance between the centre(as in the part the tyre goes on not the diameter centre) and the hub mounting face.
So imagine a wheel standing up as it would be fitted to a car and your looking at it from the tyre or where the tyre would be fitted. Find the centre of the tyre mounting part and imagine a line cutting directly throught it to the other side, the distance between that line and the hub face is the offset
So from where the part of the wheel bolts to the hubs outwards to the edge of the tyre is a positive ET and the reverse is true of negative??
A negative offset would be like mounting a wheel backwards if you could or getting a split wheel and fitted the barrel on the wrong way as this moves the centre line of the barrel to the other side of the hub face(where your wheel and brake meet)
This is all about the barrel part of the wheel, if the wheel hub face was in the centre line of the barrel this would be a zero offset, since wheels must go under a car this would mean moving the hub face towards the outside so the barrel can go under a car.
I was going to get a guide together ages ago as I was getting pm's about offsets all the time but it's fairly straight forward
A guide would be good! Be no harm to have one if you could do it. :cool:

Okay, well let me rephrase, what's a good offset that does not require mods to arches? I recall reading a lot on style 32's being the limit with the correct tyres.
RE: The BMW questions you were afraid to ask.
For what it's worth I liked the offset of the Rotas I had (et35) 8j front 215/45 and 9j rear 225/45 filled the arches nicely without limiting tyre choice, there was no rubbing, and a very mild stretch.
RE: The BMW questions you were afraid to ask.
Style 32's are an e39 wheel so they would be et20 as would RC090's, 8j et20 wheels can be run on stretched 205's or 215's without any issues but if you often carry passengers or livestock you might want your arches rolled.

RE: The BMW questions you were afraid to ask.
[size=large]i was wondering and this might be better answered by the technicians/mechanics and bmw fans with a wide range of experience with all the different models:
1: what are the really simple mods / tricks you have learned from working with bmws that you think YOU have found on your own, maybe they are known or not known by others that you have read about,?
And
2. What mods have you found that are simple bolt in/ on mods, that you have tried and worked e.g 6 series front seats bolt straight into a 5 series, or with a little work, maybe it's in the wrong thread but I'd like to read about some good tech stories or different than normal mods,
The reason I'm asking is after I get my engine transplant I'd love to try a few different ideas or suggestions on my e46 too
Cheers for any reply in advance, it might be a good read?

RE: The BMW questions you were afraid to ask.
That is a fantastic question. Well done Mick.
I'd like to know aside from the physical installation, whats involved wiring wise with fitting a e39/e46 transplant? I seem to thimk there are body modules to be used, is this so?

Anyone know how to reset these bloody things?
It's the arm thing that pushes the seat belt forward.

1 very cheap brake upgrade for E46 if you are running 280mm front brakes(316,318 320i ...) and want 300mm brakes (320d/325i/328i etc) simply change the discs and the caliper brackets. The calipers themselves are actually the same. Very cheap upgrade if you can get the brackets from a breaker.
Want to drop the front say 10 or 15mm? But keep the same suspension setup?
Fit lowering spring caps, supersport.de sell them for around €50.i have them on mine.
Afaik E90 caps on an E46 will drop it a few mm too.(not 100% sure)
