Alignment issue

I just dropped mine off also. They said it's a radial pull and they will swap front wheels side to side which I already tried and if no change then they will do an alignment. Will post back once I know more!

Interested to see what happens. I have 1900 miles, and my M4's been drifting to the right since much earlier on.

I just got my car back and they did a slight adjustment but I haven't got a chance to truly test it out yet. Will report back tomorrow and at the mean time take a look at the alignment sheet.

I'm guessing the "spec" values shown are *not* those for an F8x car. Note the front camber spec value 0.19' is ~1/3 of a degree of negative camber, and the tolerance is shown as +/- 0.5 degrees. This is way too little negative camber for the front of an M3/M4, and there's no way the BMW spec would allow a range that goes into positive camber.

This is pretty much proven by the actual measured front camber on your car. Note that it shows -1 degree 22' which is about -1.3 degrees camber -- that sounds about exactly where I'd expect the M3/4 front camber to reside. They obviously don't have the proper set of specs loaded into their alignment machine yet for the F8x.

Yes, you are correct! They don't have the specific alignment specs for the F8X's yet and they used the F3X on this adjustment.

So I just picked up my car from service with extra 120 miles and <10mpg average again... They made no adjustments and only solution from SA is replacement steering rack on order

here's the alignment sheet for the curious

Thanks for the update. Hey, at least it appears your dealer actually has the correct alignment specification update for the F8x loaded into their rack machine. Keep us posted on the outcome. If it is indeed the rack, issues like these are not unusual during initial parts production periods during a new model launch...regardless of the manufacturer.

Thank you for sharing your data with us, much appreciated!

Yeah, I'm feeling a little bummed out that they didn't use the correct specs to do my alignment but comparing my sheet to Uhmenono's sheet our final outcome is very similar.

After getting my alignment is a lot better than before, I don't need to constantly adjust my steering when tracking straight and when I let go of my steering it still goes to the right but it feels more like a tire pull now then an issue with the alignment.
