Just start at recommended pressures....then check hot temps and adjust from there....my E92 DCT with stock 19" PS2's performed well at about 43.5psi all around (hot)
#1 have fun and listen to your instructor......be safe....
The M3 is a wicked machine for the track....you'll love it and quickly become addicted...
