pecker extender

School me here! l don't understand how it helps in bracket racing. Seems like all it does is make the rollout a lot longer and thus the car run a diff (faster) number (i.e. a rolling start) but who cares? It would always do this so it seems like the dial-in takes care of that?

Now in class or index racing, I can see where it would make for a faster ET so the motor doesn't have to make as much power to run the number. Maybe helps if you're struggling to run a number.
If it’s low enough it will trip the beams at the top end which can effect the guy in the other lane when squaring up before the stripe. If they think they are ahead by a wheel the extender could be further ahead than they think and trip the beams in your favor. Like I said, it bit me once. I knew I was ahead of the guy, but didn’t realize he had a little pecker.
