Street and AutoX.

I run factory toe-in front and rear, and even sometimes ask for extra front toe-in as I despise a lively steering wheel. I want it heavy, centered and locked down. I want to the car to track perfectly straight with hands off the wheel over bumpy surfaces.

I also run as much camber as stock parts will allows.

My car was dialed in approximately like so for street use. I don't daily it but the car has been wonderful.

Front
-2.7*
1/16" Toe In

Rear
-2.2*
3/32" Toe In

Camber plates were then marked with a paint pen at that street setup as well as ~-3.5* camber in the front for easy potential track day switching.
Worth noting is when just changing the camber for the track setup, the toe will move out which will aid in turn in.

Any shop that does alignments with Bosch or other good ones will have CSL e46 M3 in the system to pick. My shop has a Bosch alignment machine and it has CSL preset. I am not sure of the specs but will try to dig it up. CSL comes a bit lower than regular M3 so perfect for guys like me who have car lowered.

Different tires also like different camber settings. The distinction will be more important for track use (lap times...) than for street tire wear.
Different suspension setups (stock, lowered, camber plates...) play a role too.
Sooooo many alignment threads!

Csl settings for a regular m wouldn't be quite right as the track width isn't exactly the same due to the csl having a different King pin than us.
