i just got off the phone with buttonwillow main office. the lady who answered said she will call the club person handling the event to find out what configuration will be used.
the track needs to know because the friday test day is always the same configuration that the club using it for the weekend runs. i am assuming it is race 14 clockwise. it is what arosc has been using the last couple years.
there is a picture of it on the buttonwillow raceway sight (
www.buttonwillowraceway.com), just click on the "track configuration" link.
i will call the track tomorrow afternoon and post what they tell me.
