1st time at the track advice.

Cudaspaz,
The way to run a 4-speed is to never lift.
I know you won't be doing this to start.
But the first limiter is for after you stage and have the throttle wooded waiting to drop the clutch.

The second limiter is for missed shifts,broken drivelines,clutch's that let loose,rear ends that explode,axel's that brake you get the idea.

Also you you should get a line lock if you don't have one already.
This helps keeping your car from rolling threw the lights.
