Bryan, the fastest race lap of the weekend was a 1:23.9xx by B. Curtis in Race 1 on stickers. I was pleasantly surprised my best lap of the weekend was only a 1/2 second off the fastest lap considering it was on the 15th heat cycle on my tires and I am historically not as fast at Cresson. I personally have never in my life run a lap in the 23's in my car.
Also, John had the overall fastest lap of the weekend in Sunday qualifying with a 1:23.134 and I think his RR's were around heat cycle 10.

I think those times show the RR holds up maybe better than expected.

I was very impressed with the speed out of the Falken's. I didn't think they would be close to the same lap times as the RR and R4 showed they were no more than 1 second slower.
