I have tried to do my due diligence before posting a question about wheel fitment. Most people running 19x10's in the rear usually have the offsets from et 20 to et 26. The reps from HRE are suggesting the following fitment for Z4M:

19x8.5 et 30 (this appears to be within the range that most people use: 32-40)
19x10 et 40 (most are running et from 20-25-26)

I'm concerned about the 19x10 et 40.

Also, interested in Michelin PSS's: This seems to be a common configuration:
225/35/19 F
265/30/19 R

Also, this set up is going on a stock suspension for now...may go with coil overs in the future.

Any suggestions or guidance would be appreciated.
