fans in this garage, don't like change. We're just skeptical of it, and we've had some really good racing this year, some of the best racing we've had in a while. We're just starting to learn how to get our cars better with the short spoilers. Nobody really wants to change, but how can you complain or argue with NASCAR? They've done such a good job the past 10 years of growing our sport and making it more fan friendly and appealing to TV and things like that. If they think this is going to help our sport grow, we've got to get in there whether we think it's right or wrong and do it with them.

But those are going to be keys to making the Chase is running well with that COT car and getting our downforce cars to handle good."

For NASCAR teams, the track has become one of the most popular tracks to test shorter to intermediate tracks on the circuit. For the 2009 season, NASCAR imposed a blanket ban on testing at any track used by any of NASCAR's three national series or its West/East (currently run under the ARCA Menards Series banner) touring events. Rockingham, unlike many tracks used in testing historically, is not on any of the series in question, and teams
