On my past M3 I ran -3.2 front/-2 rear but it looks like you're limited to -2.7/-2 at max setting - can anyone confirm? If you're not taking to an alignment shop, don't touch the rear... rotating the front caster camber plates will add roughly a full degree of camber and an 1/8" total toe out

How much toe out would increase if I just changed the plates myself

Also is it necessary to lower the ride height in front or only needed for corner balance?
Not at all necessary, mine are still set to stock

I saw some technical documentation from GM to change oil from 0-40W to 15-50W, change brake fluid to dot 4, put on lower air dams, remove water guard under hood, rear swaybar has some adjustment (any recommendation for position to start out?)
Mobil 1 15w50 although I'm hearing Spring Mountain is having great results with the GM 0w40. Definitely replace brake fluid with Dot 4 or better.
Rear swaybar leave in factory position. Drive the car and have fun!

Congrats on the ride! Comments in bold above. Cheers!

Best regards,
Dave
