Nice pics, WW, BM. What psi should these tires be run at hot, and is it allright to run them in the rain?
Pilot Sport Cups????
Road Racing/Drivers Schools/Track Events: Typically 25-28 psi cold rising to a target of 32-36 psi hot.
Damp/Wet Track/Course Conditions: For both autocross and track use in heavy wet conditions (lots of water down on the course), increasing tire pressures as much as 6-10 psi hot above what would normally be run in dry conditions may be necessary for best efficiency. For "damp" conditions (course is wet, but no standing water), pressures at or slightly higher than the high end of dry-track recommendations will likely be most efficient. Car setup and driving style in the wet is very important, so some experimentation may be in order.
Try to get them to about 32-33 hot which will depend on the track temp. If it is damp and not raining do not change much from that. If it is raining and there is standing water the MPSC will be a chore to handle, but add psi as state above...

George I had them at 27 cold for dry. Start there, they seem to like that. It was never really wet last week just damp no standing water so if it is raining start with the 6lbs above the 27=33, they wont heat up much in standing water. Also be aware that they will feel much different than your F1's on the road. They have a much stiffer sidewall, they are lighter, wider and are on lighter wheels so therfore much less unsprung weight. Gonna want to wander a little and not be quite as smooth as the F1's. you'll see, no big deal just feel funny at first.
