Just returned from BW with POC and verified what I had thought to be the difference in lap times between Config. #1 CW and #1a CW. On Friday, the a.m. session was on #1. Afternoon was on #1a. Everyone was 3+seconds slower on #1a. It was as valid a comparison as can be made since so many different drivers were involved and universally experienced similar results.
Have fun at Pahrump --wish I could make it but unable this year.
