Of course many things at play, driving style, type of track, track conditions... On this particular day it was 95F ambient and hard to keep tire pressures and temps in check.
That seems to be in line with what appears to be too little front camber in factory form. I was think about -2.5 up front and tires would likely still wear evenly on street. I'll do a little more research. It may be a hybrid between what the M2 crowd has been running and what the m4 with adaptive dampers run. I'm having track connect sensors installed at delivery and will also have an alignment done. I learned my lesson with the last car trusting it was good from factory.
