Tire Pressure
What tire pressure should I be putting into these size tires:
245/40/18
255/40/18
Normal driving and a road course.
Anyone share their experiences?

Tire pressure depends on the tire, wheel width, alignment and so on. Use recomended pressures for the street. On the track, start with 4 or 5 psi over recommended settings (maybe even up to 10 psi). Then, use chalk or white shoe polish on the edge of the tire to get the proper tire roll. You may have different settings front to rear. Lastly, you will have to change the balance for feel.

The only reason for running the rears a little below the fronts is to 'tune' away a small bit of oversteer. On the track, you can feel a difference.
On the street, I run 33psi front and rear, for no apparent reason. I can confirm (via my aftermarket tpms) a 4 to 5 psi gain cold to hot on the street.
