The Rules at most tracks say you can have 1 helper so why not use them.That's an extra set of eyes to help check every thing like oil or lose parts left over by other cars. Unlike a lot of people I can load my race-car in the trailer unload it and race it at the track all by myself I need no help what so ever,but it makes everything so much easier when you have good help.At the present I have 2 of the Best that I have ever had in my 25+ years racing,so yes they are going to be out there with the car every time.
If you want to Win races you have got to be on top of everything that is going on,and 1 person just can not do that.
