Sweeet.
Use some chalk or white shoe polish to see how much you are rolling over. I start a wee bit high, like 38 psi HOT(mebbe 36 psi before first run). A lot of tires have arrow markers on the sidewall that will tell you if you are flexing too much. I will knock it down 1-2 psi per run until either the car starts to feel greasy or I see fresh scuffs creeping onto the top of the sidewall from the shoulder. Then I back go up 1-2 psi from that point and look at tire temps to evaluate alignment.
I ran 40 psi up front last season on the normal shmormal goodyear eagles to keep the tire churning around hairpins. The rears were maybe 36.
RE-71s are stiffer, you will probably end up running much lower pressures, especially if you have a good dose of negative camber.
YMMV, just my own experience, I'm sure there are better ways to optimise pressures.
Good luck this upcoming season! May I ask your wheel specs? I'm planning a 305 square setup too...
