10 inch wide AP2V2s
Just a quick update. Drove the car last night, definitely stick better! I'm still in the greasy part, break in, of the tire. I'm am amazed. I will say this though, the weak part of the setup is not the tires now, end up slipping the clutch slightly not paying attention getting it from a stop light. No launch, just not paying attention on getting out of the clutch all the way before accelerating.
With the offset and width how it is, I have no rubbing issues to report back.
Will get a round of pics on Sunday

Here is a simplified explanation. Think of half of the wheel in cross section as the capital letter L
L
Now imagine that the top of the letter L is the top of the spoke where it is attached to the center hub of the wheel. The vertical leg of the L is the spoke. The horizontal leg of the L is a simplified version of the outer part of the wheel around which the tire mounts (yes we all know it is really curved but it doesn't matter for this discussion).
Imagine that the L is hanging in space suspended by the very top of the vertical leg. When you apply force to lift or lower the horizontal leg of the L or push the lower leg of the L into and out of your computer screen, you simulate the forces exerted on the wheel spoke while driving, cornering, hitting bumps, etc.
Now..... lengthen the horizontal leg of the L (including it's wider tire patch around it) and do the same thing. SEE THE PROBLEM? You dramatically increase the forces on the spoke because you have lengthened the lever arm. The wheel spoke is designed to withstand given forces and you are changing the design parameters for the worse.
Does that explanation help?

ok, well you have just answer the first question, what about the second? this may get a little off topic. do name brands actually strengthen the spoke due to the increased length? i agrees, with the thickness of the spokes and how many there are of the ap2 v2 rim the op may be safe. but i have seen plenty of guys on here with large width rims around 10 inches or above. why aren't those guys complaining of cracked spokes?

There's always one. I agree w the post on the wheels damaged on the track. Those spokes are very narrow and the added stress was likely the culprit. The ap2v2 wheel have a much more solid design, hopefully this doesn't happen. Time will tell, but my bet is that it will be just fine. I would not have done it otherwise. I'm not and idiot and do my research. I thought id share since I haven't seen anybody try this yet that I have seen.
Ultra sleeper status ftw!
[QUOTE=ILoveMYHonda1984,May 25 2010, 12:01 PM]Haha, why? Guys on the BMW forums do this all the time. No failures to speak of. Everybody talks shit on rotas and always pulls up that one picture of the broken slipstream.

Cudos to you. I've got a friend who's been planning this mod for over two years as the third phase of his build. He's also done stress tests on the AP2V2 wheel at a local machine/fab shop in preparation for it. You could have gone even wider if you'd liked. 
P.S. Who did you go to for your spacers?

The spacers are Project Kics from Evasive. 20mm with the optional hubcentric ring.
Here are a couple pics from Sunday. I guess I still need to get a simple straight on shot. Have to wait till I get the wheels back from getting the face refinished. One had some curb rash, and I wanted to test fit before I spent any more on them. Should be back wed or thursday.
