The new tires were amazing all weekend . ran a set for 2 club races and my son ran my 2012 with they same setup/tires all weekend at the us indoor champs he had fast laps every round and one tap cost him tq. And had the main raped up till last lap where he got stuck in a back marker which cleared the way for bill sydor to take the win . this kid(Matthew Lyons) + xray+ride tires = super fast car!
