how do i launch harder and better with the smg trans in the m3?

Answer 1

Launch control - Turn off DSC, engage sport mode, and put SMG in S6. Put it into drive, put your foot on the break, and push the stick forward (and hold it). Slowly press the accelerator all the way to the floor. Remove your foot from the brake. When you release the stick, the car will launch.

Burnout mode - do the same thing, but quickly press the accelerator to the floor.
