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)

I'm on factory settings and it seems "fine" to me...even today on my Alpine snows... I often drive/corner quite aggressively and the car bites in hard. Even today on my snow tires I had chassis wobble where the tires maintained grip in a very hard fast >90 deg corner. Scarred me a bit....but grip was maintained. I'm no track driver so I don't discount room for improvement and defer to those who know/understand better....but I'm happy with it...

PS - also 10K miles....most (but not all) pretty sedate....tires look good with no noticeable funkiness in wear...

Make no mistake- the first time I ever drove this car on the stock alignment I thought to myself “ this is the best car I’ve ever driven”. It’s actually surprising that turn in, roadholding, and feel can actually be improved!!! YMMV, but i for sure highly recommend it. $200 for an aligment with really no downside (see my comment on 10k miles and still nowhere near worn out)

Kind sir- could you provide your alignment report/sheet so others might partake in your 'best of both worlds' settings? Thanks in advance.
