I run RA-1's, but since we're in the same class, I'm no telling you my secrets!
JUST KIDDING!
The best pressures seem to be around 37 to 39 front (hot) and 38 to 40 rear (again, hot). Depending on how your car handles (under or over-steer) you can adjust the grip front to rear accordingly with pressures. Since I have a bit of oversteer, I run the fronts lower to dial-in a tad of understeer as compensation. Remember: our individual car's suspensions are set-up differently
.
The Toyo website indicated pressures between 37 and 40 (hot) to be "optimum."
FWIW: I start mine at 32 cold-front and 34 cold-rear.
See you the 23rd?
