992 GT3 on Monticello Motor Club North Course

1st laps on MMC North
Testing protocol: Car cooled down in pits; tires back to ambient temp; 1 out lap at 70% to warm up engine and tires, 1 hot lap to raise tire temps and pressures and 1 Ultimate HotLap.
It on the next lap car can still manage same late braking points will try another Ultimate HotLap if the Timing Deltas are favorable.
Matched the Road & Track PCOTY Laptime on the less grippy OEM Pirelli PZeros (Porsche, obviously, supplied R&T with Cup2Rs)
My best guess is 1:19.9 is possible on those tires on a Cool day. This machine is an impressive la-time beater for "only" 510bhp
