Wayne,
Yes, that was another NASCAR rule. No team may have over 4 cars. I wouldn't be surprised to see him cut back to three. Ray Everham has sold most of his team and said he is not going to be very active as he has just gotten burned out by the continual crap. Give NASCAR three more years of their no racing and all show crap and they will be hunting for a way to survive.
Throw out that dam top 35 rule, let the teams get cars from any dealer and make them safe and then do whatever work they want to make them better like they used to so the team that makes their car the best wins. Do away with the dam yellow phantom caution flags so they can get in their TV commercials and race. Next step will be NASCAR will script who is to win which race. I don't even like it any more and didn't watch any of the stuff so far except the 24 hour Sebring race.
Ron
