E30 M3 with 18" hamann HM2's 18x8.5 ET38 with no rubber yet.
stock susp. possible drop in future (max1")
question 1: what thicklness of spacers do i need? 15mm?i want a flush fender look
question 2: what size rubber? i was thinking 215/40R18 allround.

thanks,

On my 8.5x18's, I run a 20mm hub-centric spacer(out of the box they're 38mm offset). The tires are 225/35r18 Michelin PS-2's.

You probably need 20mm spacers, but I suggest you go at least 18mm. I got a set of of 17x8 wheels and I'm running 18mm spacers.
For my 17x8 wheels I'm running on 225/40/17 tires all around. For the best fit, I think you would need 235/40/18 but minimum 225/40/18 size tires. With 215's you would have to stretch the tires in order to make that fit.

Hey Cris,

Mind if I try your 20mm spacers, I'm curious what my setup would like like 5mm further out. I'm at -2.8 camber and the wheels really look tucked in now.

Stock od is 23.9

235/40R18 is 25.4

225/40R18 is 25.1

225/35R18 is 24.2

If you opt for the taller tires, you will have clearance issues at the inner fender well.

225/40/18 and a 25mm spacer is badnews. thats how the PO raped my front fenders.

When did you want to try them?

Cris

When ever. I'm in no hurry. Just one would be enough since I know the back would fit, I'm just concerned with the front.

p.s. you think I would need a second set of pads for the infineon weekend? I'm considering going up friday night, would you be interested in splitting a room?
