[s-cars] BMW Rear Camber

[Mark Pollan]

Interesting indeed and thanks Evan.  To build on Igor's question, is there
an optimization formula for determining toe for a given camber?  Optimum
being defined here as minimizing tire wear.

Regards,

Mark

1.3 negative in the front with slotted plates and with very little room
remaining

That is a very interesting observation, Evan. I heard the same thing. 
How much Toe do you have in the front?
