Okay I've been reading through this whole thread and I am now completely confused. I understood my 2006 Z4 3.0si stock wheels were 17x8.5 with 225/45 tires. The ET I read was 40mm. I want to get 19x8.5 F and 19x9.5 R. So if I order the fronts with an ET of 35mm they should stick out 5mm more than stock and the rears with a ET of 40 they should set in the same as the 8.5 stock but come out the extra 1" or 25mm. So why am I seeing people dropping the 9.5" rear wheel to 25-27mm? That would push them out like 40mm from stock? AGHHH

Help please. I just want the wheels to be close to flush but error to the inside not sticking out and no rubbing. What should my ET be?

19x8.5 ET35?
19x9.5 ET40?

BTW, I plan to run 245/35 and 275/30 tires

Thanks so much for the help.
