Suspension question

[RKS]

My understanding is that both 4 and 5 BWs come with aggressive camber and toe setting that are optimized for track use at the cost of tire life.
How much "handling" am I missing with a non-track alignment? I may try autocross this Spring but would rather have tires that last more than 12,000 miles.

You will be fine with a street alignment. You "might" be autocrossing for fun, not for prizes. That 0.05 seconds you will be missing is not going to make any difference.

I disagree. I went from the standard street alignment to kind of hybrid street/track alignment (-2 deg front, just adjusted at the knuckle-not strut tower adjustment, -1.75 deg rear, very slight toe in-essentially zero toe with a toe in bias) and noticed a significant difference in turn in even on the street. I did not track the car prior to changing the set up but if its noticeable on street then its likely more so on track. But i guess it depends on your definition of “fine”. The car will work of course with the stock alignment but in my opinion youll be pushing understeer quite a bit.

I am at 10K miles and tire wear looks perfectly fine (9750 miles street 250 miles track)
