Would like to know this as well!

honestly, i wouldn't dial your camber and toe to some arbitrary spec. run the spec that makes sense for your uses. daily drive? don't really race at all? degree and a half and either a little toe in, or zeroed all around. race it? run some laps and check the temp across your tread to figure out the best specs.

personally i liked ~2 in front 1.5 rear, zero toe on my sti. I can't see my 1 ending up running anything too different

Yeah I think you could get -1.7 on the front camber with stock M3 stuff and I'd leave the toe at 0 front and rear to save your tires. -2.0 front camber if you can. The backs maybe go -1.0 to -1.5 for the camber.

Check 1M specs too regarding toe (e.g. if there is a little toe in on the rear, I wouldn't hesitate to run yours that way for stability). Agree that zero toe up front is a good place to start.

In the end, this will depend on your suspension, tire choice, and use. And the specs on other cars, especially non-BMWs, aren't necessarily pertinent.

zero toe all around is totally a preference thing. some guys run a little out in the front, most run a little in in the back to keep the skittishness down to a minimum

With the M3 front arms, the max the alignment shop could get me was -1.1 degrees on the front. That is without drilling the pins (which would get you a few more tenths of a degree) or camber plates.

My rear is -1.5 but I'm having coilovers installed tomorrow and will probably have it aligned to around -1 all around, that's really all you need up front (as far as I remember there is no toe on the front and the rear has toe set to the stock values, whatever they are) my car absolutely does not understeer, but I am running 225 Michelin Pilot Super Sports up front and 35psi all around.

at -1 degree with 225s you will understeer like crazy still. I don't think you're pushing your car hard enough if you aren't getting understeer and not running camber plates. I had the m3 arms, alighment pins pull and everything pushed in getting about 1.5 degrees of camber on the front and still destroyed the front 225 pss outside edges. Now with my coilovers and lil more than 2.5 degrees up front i'm finally getting even wear out of the tires.

With the M3 front arms ! After the alignment with the M3 spec, That is drilling the pins, I got the result like this on the photo. The left and right dont get the balance. Anyone can help me?

Sorry - no idea about your questions.

But, wow! Is the top part of the picture showing "before" with a toe-in on the front of 2 deg?

It looks like they reduce the front camber from 2 degrees down to 1 and 1 1/2. Did you want maximum camber, or minimum camber?

I think the 2 degrees from the top of the sheet is actually the toe. The box for camber measurement should be above that and it cut off in the picture.

Yes you are right!

Actually, I want to set it to balance only

Maybe you need to learn how to drive? (bear in mind I have no idea who you are, I'm not trying to be a dick) but I've seen 911 Turbos and Exiges disappear in my mirror at the last track day I took my car to and that wasn't even with the Pilot Super Sports. I wasn't saying that you could yank the steering wheel at 90mph and have perfect grip, I was just saying that -1 degree of camber up front and a very tiny amount of toe out was all it took for my car to end up fairly neutral.

I will say that my driving style favors oversteer, I focus a lot on smooth brake release and turn-in so I almost always run out of grip at the back end first, even in the 997 Carrera S.

Great call on the top if the sheet missing Canucker.
I run 245 PS2s up front with -1.5 camber and zero toe for the track and the car still understeers. That's with Dinan Stg 2 susp, and full M3 components in place. I will say the E93 rear bar helped out a lot, but the car still needs more camber up front. I think -2 1/2-3 at the track would be great. Some adjustable camber plates for the front are a must for any track junky/weekend warrior. Any one running -1 of camber up front that doesn't notice the understeer, isn't pushing it!
