My real answer is I don't know. Don't have experience with that configuration. The typical driving school response is take your manufacturer recommended pressure (I think 32 psi) and add 5-10 psi. So say try 38-40 psi. That should be OK since a RE050 has a max tire pressure is 50 psi. This "driving school" answer is due to that typically most street tires have softer sidewalls, so require more air pressure to prevent the sidewalls "folding" over and screwing up the tire patch. Also note that this is cold tire pressure. Tires get hotter when run hard, heating up the air in the tire, increasing the pressure. So, depending how "good" you are, tire pressures can vary quite a bit on the track.

I'm going to assume that you're a novice driver, so don't be offended if you're not. Don't worry about all this suspension tuning stuff for now. The most important thing for a novice is to have a safe car and worry about learning car control. The driver is the most important thing as far as controlling oversteer and understeer, it doesn't matter what the suspension settings are.

After getting control of the driving basics and you can feel what the car is doing, you can try out changing tire pressures. That's free so no big deal playing with it. Next alignment settings. Next swaybars if necessary. Lastly, shock/spring/ride height combo. This is the most complicated tuning method and is so easy to screw up the stock car handling if you as a driver can't read if the car is working well.
