What adjustments really need to be done after the burnout?
Does the wheelie bar height change that much after the burnout? Why can't you just set it at the trailer beforehand...seems like if you've done enough testing, you'd know where they need to be before the tires get hot. I've worked w/ some fast grudge cars in the past and we never did a thing to them after the burnout.
A 1/4 turn valve where the driver can reach it eliminates needing someone to turn on bottles.
No matter how poor visibility is in the car, after you've made some passes you should have a feel for where the car is in relation to the beams.
I think for the vast majority, it's silly. You have a bunch of people in your "crew" wanting to feel important.
