What's the largest width I could put on my E36 328i?

Looking into an upgrade from stock and found factory E46 rims, 5-Spoke Motorsport rims. Sets only come in Staggered 17x7.5-Front and 17x8.5-Rear. I'd like to go 8.5" all around, would this cause any fitment problems or would I have to roll my fenders or use spacers?

Anybody?

I'm running Kosei K1s (17x8.5, et42) with 40/245 tires all around. I've rolled my rears, and there are no issues whatsoever in the back.
In the front, however, I can't set the car down without a ton of camber dialed in, the wheels just won't fit. Even with a ton of camber, I still can't get the wheels to full lock, they rub pretty hard. I imagine I'd need a 15mm spacer + the camber to get a full range of motion out of the wheels.

I have 17x8.5 et41 style 32s all the way around on my ti with 245/40-17 Hankook ventus v12s. Suspension is bilstein sport/H&R sport, no fender work done. Nothing rubs in the front or back at all. Up front, the wheel is close to the strut but no need for a spacer.

Hmm. Sounds good to me, thanks fellas. Yeah I'm looking to run 17x8.5 style 68's all around. When you guys take hard turns, does it rub at all? I run my car in the canyons but so that's why I wanted a wider tire. If I rub at all that'll slow me down, I want wider road coverage with style as well as peak performance. Anyways, thanks peoples. Anymore input is welcome as well. :-)
