Your rears may be ok, but the front will probably sit in (depending on what offest you are using). The factory offset on the new M3 is ET29 on a 8.5 front wheel.
To the OP, since you are still in the process of looking for wheels, I would wait another month or so, so that further test fitting on the car can be done and some further fitments can be confirmed.
The M3 will be a whole new fitment, just like how the current gen non-M 3 series was a whole new fitment, especially on the rear.

i'm looking to get the 08 m3, and i'd really like to put the ssr's on it, but there's no info on whether they would fit or not.
they're 19", btw
