Tire wear
I am getting weird tire wear. Camber is -3.5, toe is 0. Tie rods are new, bushings are new. Alignment is fresh.The inside of each front tire is wearing. The driver's inside wear more than the passenger side. Thoughts?
M3 is always the answer.

Maybe 4 wheels aren't so bad after all... wickett.org

wow, channeling jeffman, eh?
I agree that the alignment sounds off. Maybe it settled, or they didn't tighten the tie rods properly. My guess is toe. Ballasted, I assume?
If you don't have a repeat-alignment plan, I can't recommend Texas Track Works too highly. They will still give the $135 forum price for 1 yr unlimited if you ask. Maybe not to a BMW douche...

Over-inflated?
How do they smell?
Balance?
On the track, I am fearless.
If you were as slow as me, you wouldn't be afraid either.

too much camber and possibly too much toe in/out.
3.5 is ALOT for a car that sees any amount of street time...

I thought camber did not wear tires but toe did.Originally Posted by fwMiata

only works to a point... with 3.5 degrees of negative camber, you must have 0 degrees of toe to a high degree of precision - probably higher than the car can attain.

Not sure I agree totally. I run -3.3 and I get a consistent zero toe, at least on a good rack. Camber wear tends to show up more as uneven wear across the tread, not cupping.

3.5 negative will wear inside edge unless you corner hard often..............toe in will also wear inside edge.
Agreed, but toe-in will result in cupping.

I don't think its alingment related at all. I think its because the last few events you've done have all been predominantly CCW.
Let me guess - if you look at the rear tires, you're getting similar wear patterns. Am I right?

No. These are the tires I use to drive to track events. I have not autocrossed on them. My autocross tires don't last long enough to see wear.
Just has alignment checked and toe in the front is still zero.
Could this be from the camber and the inside front tire dragging when I am turning?

Like in this image.

If ^ is right, then sounds like you might have some of the typical worn out BMW bushings and rubber bits. You getting any clunking? Weird handling on broken pavement?
All bushings are new. Tie rods are new. Wheel does not vibrate like it is out of balance. Nothing is bent. No clunking.
M3 is always the answer.
Possible bad batch of tires? I also agree that -3.5 seems alot for street driven tires and can wear out the insides in a hurry regardless of toe..
Send the pics to the manufacturer and ask for their comments.
