Also guys i know there was talk after the last event that they will be tightening things up in regards to who can jump in the car. e.g. they will have to be signed on ect and there was the possibility of the signed on co-drivers getting a wristband put on by the people doing documentation and it was going to be checked at the beginning of each run. They noticed drivers swapping with co-drivers and co-drivers with different names in the cars competing when there was only one person. So save the problems, if you want 4 co-drivers have all 4 signed on.
Also Burke can jump in if you want, I am lighter than Alex
