When the car went to the seven-post rig, various changes were made to improve the data the rig generates. These changes were left in the car for the race at Concord. As an untested setup, a lot of work went into sorting it out and making it work in the Friday and Saturday practice sessions. The crew did a very good job working it all out to end up with a very decent handling balance. I'm unsure as to the effectiveness of the dynamic balance of this setup.
