oh well... guess no one went from here. it was a great day besides the 105 outside temp :)

as this was my first track day in the is300 i was really surprised to find out the capabilities of the car. the way i have it setup right now is very neutral and the car just stuck to the ground. there were a couple of times that i slid a little, but it slid all four wheels and kept the line.

even my instructor gave me props on the car. he was pleasantly surprised with the handling of it..... while he was scaring the shit out of me by running through the track like a pro. wow sitting in the passenger seat is just amazing watching a pro.

i am very impressed with the is300!!!

btw... the outside of my tires were never really scrubbed that hard. most topics i read all complain that there is too much scrubbing on the outside. can someone explain.? TIA... i was running 45 out of 51 psi all around.

Sounds like fun. To answer you tire question, you should not be running such high pressures for road racing events. 32 - 33lbs (cold) should do it for stock tires. High pressures like you mentioned are only ideal for autox where your tires don't have time to heat up.
As your tires warm up after a couple laps, they will raise approx 7lbs. Your outside edges are wearing mostlikely due to alignment. I am running close to 2 deg of negative camber to get flat contact patches, thus even tire wear.

Isn't it great being a passenger with a good driver. I have had instructors drive my car faster than I ever thought it could go. Very humbling experience.
