Slow-
Most guys won't cut the teeth in mod, the belt is more likly to slip, If you do you will have to run it tighter, in turn your drivetrain will no tbe as free, Most of the guys do this in stock or 19T to help free the car up in the corners and maintain better corner speed. It also makes the belt a little more brittle. I broke a black belt two weeks ago in 19T that I had cut the teeth, You are probly better off just leaving it.
