To put things into perspective, Optima arranged for several “benchmark” cars to run in the event. One of them was the ’04 Porsche GT3 owned by hot-shoe driver Mario Matos representing Bowler Transmissions. Sporting R888 Toyo tires the German rocket knocked down a best time of 1:54.2. Fast, but there were four cars with faster times. Another newer car, this time actually competing, was a C6 Z06 driven by racetrack veteran Steve Kepler. It’s a freakin’ Z06 on Goodyear Eagles driven by someone who knows what he’s doing—now that’s a benchmark to shoot for. Still, two rides turned in faster times than the Corvette’s 1:53.7 best lap. One was our ’68 and the other a ’68 GT350 owned by Kevin Sittner. Kevin runs the Mustang in vintage racing events and was a real contender for the crown, but an engine oiling issue took him out of the competition early.
