Went back to Sebring with a set of Goodyear F1 RRR tires, this is the same tire that Camaro uses on the ZL1-1LE....what a vast improvement over the Michelin Cup 2 tires. Apologize for the camera view, I did not know that it had moved and was at angle until afterwords when I went back to review the laps. Was able to make the adjustments for laps run later that day. Also, brought out the Shelby GT350 and ran a 2:25.25 with tires that had multiple track days (near end of life)...I am thinking a 2:23 with a set of new F1 3R's on it!
