I think they might be possible for him... The NSX liked this track if you were able to stay on it, and hitting the inside apexes a little aggressively made it capable to drift very nicely around turns.
Keep in mind that he did one more pit than me, which indicates he used RS tires for at least one stint(there's no way you could squeeze out LESS laps per tires than I did), and was still .4 seconds slower than my "fastest" lap with RM tires. I can be over a second faster on my RM tires than his fastest lap on RS tires...
But who knows for sure.
