Just to clarify,
1) I chose to ignore the 53/47 weight distribution
2) I realize everyone says we all believe our fr-s/brz weigh ~2800lbs but the GVWR sticker on the door is what it is. Is it possible the car weighs 2800lbs dry and then when you add all the fluids, it gains 200+ lbs???
3) The comment about using a tire pyrometer is spot on. On my next long road trip, I will measure the inside, center and outside temperatures of all the tires. The only caveat is that I am running -1.0 front neg camber and -1.7 rear neg camber, so the insides should be a little hotter.
4) Ideal pressure can be for both handling AND comfort. I have done my share of track days and SCCA racing and most times the starting cold temp is ~30psi and hot runs around 35-36 for most production cars. Sure there are instances when a hot temp of 38 psi can be the target, but when I ran my Michelin Pilot Sports on this car, the ideal hot temp was 35-36psi. Obviously, if I set my cold temp to 31psi and drive around, they will likely warm up to 34psi. Why should I run 35 psi cold and have a tire at 38psi hot when it won't likely improve my grip AND feel like I am riding on marbles?
