My fastest finishing time with the NSX is an 18:22, every lap after 1 is a 1:49.xxx, either the car is ridiculously consistent or all of the sudden I found my zen. With the one stop I managed to get an 18:32, so the no stop is the way to go for sure.
One thing I will say for sure, people are ridiculous with the bump drafting and dive bombing in this combo, I almost hit reset earlier because of people just being careless (spinning out and coming back onto the track, bump drafting, dive bombs, using my bumper as a brake) after a big scare I got placed in the lower lobbies with automatic pole, easy wins. Once I made it back up the 90+ lobbies, people started driving like idiots again, if you’re not in the top 5 for qualifying it is completely pointless for you to try to do a 1 stop, your pace will be at best 1 1/2 second faster than the people no stopping and the pit lane is way too long, you’ll just end up outside the top 10 if you play that strat. The one stop is only effective if you can build at least a 12 second lead by lap 6.
