As illwillem suggested it is you who is letting the car push then get loose....I have been on track with fast guys in stock cars and they are in control regardless of grip levels..they are working hard with lots of corrections, fast hands and twinkle toes.....optimize your brakes/tire pressures, and get seat time with good instructors..... find one with a in car communicator like chatterbox ect ...a baffled oil pan may not be a bad idea if you start to push on R comps.Have fun!
True, I should hone my skills on the stock setup before I try to change the handling characteristics of the car. I don't plan to go R comps while the car is stock, so I'm guessing the baffled oil pan isn't necessary?
I'm in for whatever you guys decide on
I'm leaning towards Dec. 11 track day. We'll be well rested with a full belly.
I agree with most of the comments given so far. 45psi is bit too high, and if you waited 30 mins or so between sessions to drop the pressure to 37psi just before your next session, it's likely your pressures were still too high. As others have said, you need to check your pressures immediately after coming off the track, preferably with little to no cooldown.
Are you on stock 205/225 width tires?
I'm not a huge fan of HP+ pads, I would go with something a bit better.
Overall your driving looked pretty good. The NSX is a well balanced chassis and does what you tell it to. Heavy trailbraking is good to rotate the car, and it actually does, but if you didn't want that entering thre corkscrew, you need to back up your braking point to not trailbraking (and rotate) as much when turning in to the corner.
I would hardly call your moments "big snaps", you didn't let them get that far out of whack and caught the slides fairly early. Your big OS moment in T11 was from trailbraking, unloading the rear, upsetting the car over the curb, then aggressively getting on throttle. Keep in mind if you do get oversteer, DONT punch the throttle. That's a really bad habit to get into. As skip barber teaches: "When in doubt, both feet out". As others have said, keep learning the car. Most of the issues are self induced.
The standard size is a 215/265 on a 17x7.5 and 18x9.5 personally I'd go with a 17x8 and 18x10 and use a 275 rear tire.
+1 on seriously considering a baffled oil pan sooner than later.
I'm a bit surprised you were having heating issues with stock power. Not sure if your radiator is just old and clogged, or if the radiator fins are all smashed in to reduce its cooling ability.
I waited around 5 min after the first session before dropping from 45psi to 37psi. Next time I'll try to check even sooner. Good tip.
Yes, stock 205/225 width tires. HP+ pads aren't perfect on the track but I plan to wear them out before trying a better pad. I've heard good things about Carbotech XP10/8 front/rear.
Hmmm, I typically make a conscious effort to brake in a straight line before entering the corkscrew. Maybe I just carried too much speed on corner entry. Next time I will try to set up pedal cam so I can review my throttle/brake inputs in these situations. It all happens so suddenly that it's tough to remember what really happened.
Question on the topic of throttle application once the car begins to oversteer - I thought the right idea was to manage (but not floor) the throttle to keep a bit of weight on the rear while countersteering, so the car will regain rear traction. I assumed that letting off the throttle completely would keep the rear end too light and more prone to swap ends with the front. Correct me if I'm wrong.
