Offset difference between 318ti and M3 rear end

[erik325i]

Can somebody tell me how much farther out the 318ti trailing arms/hubs stick out compared to M3 parts?
I need to figure out how a set of wheels is going to fit on one of my cars.

Thanks

Wow, that's more than I thought. So it's like I'm permanently running 27mm spacers.

hub just extrudes that far out

[red911turbo]

so all the extra width in the hub itself, correct?

[Aptyp]

yes. Trailing arms are dimensionally the same (except for the size of the bearing), but hub sits that far out and rotor is that much deeper.
