Thanks for all of the advice, guys! The weather here in southern Ontario is hot & muggy - currently 27*C (81*F) and it's 8 pm. I'd imagine the daytime temps to be at least as hot when I go, but maybe there will be a cooling spell. The track I'm planning on going to Shannonville Motorsports Park (
Shannonville Motorsport Park Inc).
I think I will hold off on any purchases for my first day, but I will check all fluids, tire pressure, lug nuts, and I'm planning on changing my brake fluid as it's never been done.
@threeseventy, I'm going to save your note for later haha, you've got a lot of good advice there. The one thing I want to avoid is any irreparable damage to my car. Sounds like if I take it easy and monitor my temps, I should be OK.
