    Camber: -1.0 - -0.1
    Caster: 4.7 - 6.7
    Toe: -0.2 - 0.1
    Front Total:
    Cross camber: -0.3 - 0.3
    Cross Caster: -1.0 - 1.0
    Total Toe: -0.4 - 0.2

    Camber: -2.0 - 0.0
    Toe: -0.05 - 0.35

    I'm not a car expert (though honing my knowledge rapidly with this M3 wait lol) but it looks like the alignment has held pretty well, right? Did you have this checked because you had a problem? After how many miles was this done?

    I heard some manufacturers add a little negative camber to their specs so that the car will handle better on the turns. But I am concerned this will cause uneven tire wear. I plan to tell my alignment shop to adjust my alignment for maximum tire life the next time I get my car aligned.

    The specs you posted are not YOUR alignment specifications. They are the allowable range of specifications for each measurement.

    For example, your left/right front camber is -0.5 and -0.7 (actual), not -1.0 and -0.1

    Yes, the alignment seems Ok, I did not have any problems but put new tires and wanted to make sure the alignment was within specs. Car has 6800 miles.

    I never intended to imply these were my specs, and don't see why people will be interested in my car specs. These are the model specs, my values just happen to be in the report sheet.

    Thanks for posting those specs. Helpful to know once I receive my own M3 someday (Sept '16 reservation ... yeah I know ...).

    Is the camber adjustable on Model 3s? It's not in a l
    It all depends how aggressively you corner. If you do all freeway miles then zero camber might work but if you have a little bit of fun around corners then you need some negative camber to keep tire wear even. I run -2.5 degrees on my autocross car :)
    Toe will always wear tires more but there are reasons for non-zero toe as well.

    One might just caution people without deep pockets for tire budgets that 2.5 neg on a street car is costly. And in terms of toe, are you talking toe in, or compensatory (with lots of neg camber) toe out?

    Toe in. Helps with corner exit stability. It’s a car used almost exclusively for autocross. Tire wear is very even except for one of the front wheels where I’ve hit the adjustment limit at 1.5 degrees for some reason.

    I've also had an alignment a few months back after lowering with TSportline Springs (1 inch drop) with a local shop that specializes in exotic cars and Teslas (Model S & 3) No issues with abnormal tires wearing. Normal wear and tear after 7,000 miles.

    One question that you might be helpful around is: What can you adjust and not adjust on the stock suspension? It appears that rear camber and toe are not adjustable, a good reason to get the MPP parts. But is even front camber adjustable? Front toe has to be adjustable - would be the first car I've ever seen without it if not? Please advise, as you seem to know the suspension well! Thanks

    Only thing that is adjustable is front toe. Need adjustable links for rear toe and camber and probably need adjustable upper control arm for front camber.

    Ah nice, is it just with that eccentric bushing?

    I think the bushing itself is not eccentric. The washers on the bolt are eccentric and can be rotated to move the position the the bolt clamps the bushing.

    Woops, originally commented thinking it was front and therefore thought it was a Camber adjustment. Removed original post.
