I`m lucky in one aspect. mine are equally centered on zero ,both sides, at -2.4. MCA and have a neat mix and match (crash bolt?) base camber adjustment system.

I asked when it was aligned how much and which way toe would would go if I added more negative camber. I don`t remember now because when told it was not enough to worry about. I would like a bit more negative camber for the track events next two w/ends. I can easily return the setting afterwards.
The amount of camber before an event is also a ballpark figure. It will change depending on the track, the tires, the drivers aggression and more. So i guess I will just adjust myself to suit tire wear/temp and get a figure next time at the aligners. So I can run a street/track compromise that won`t kill tires quicker than necessary.
