Ken
How old are those tires I know your dad doesnt race that much. And tire rotation? Probably not but how knows. You have done enough cal trac install/setups Im sure thats not it. Did you ever notice this before like when you watched your dad drive or perhaps review any old video you may have?
Any way Ken did not mention in his post that despite not having driven his dads care but once years ago and not having raced himself for a year--
He managed to race down to 6 cars in a tough 70plus car field at Gateway. He took out the Pro Class champion in round 4 that almost cost him a Championship on the final nite. So nice driving Ken! For him it IS just like riding a bike--------
