M3 sedan: How do fit +49, 17x9.5" wheels?

[Dakine M3]

Picked up a wicked beautiful set of OZ's from Jonah (thanks dude) that was intended for a Vette. As I mentioned the offset is +49 and would like to have 245 square setup. I plan to mildly roll the fenders as needed. Wheel gurus I need your input.

I run 18x9.5 et48 out back. It's a very tight fitment to the inside. You may want a 5mm spacer. That's my recommendation. I also run a 255/35 tire.

I have searched the forums more than I ever and have arrived at the proper size. With a +49 offset and 17x 9.5, the fronts will need 25 mm spacers in front and 20 mm in the rear. With Vorshlag camber plates i suppose I can fit 235's (maybe 225's for stylin') and 245's in the rear. Anyone else with any experience on this fitment? Chime in wheel whores...much thanks.
