If you want 19" then only Cup + or Cup +N. These are not as grippy in the dry as the regular Cup (not +) tires as these have less negative thread.
The only 19" Cup (not +) is the 265/30-19 as far as I know: ok for the front but not wide enough for the rear.
In 18" you can find the better Cup (not +) with more choices for your M3. These are awesome grip-wise and they last relatively long.
