I'll bet this weekend was a little more expensive than a track day
I'd spend more money doing track days than racing. I do more laps at a track day which means I use more tire which is the most expensive part of this sport. If you constantly practice on used up tires your never going to figure out how fast you can actually go. You can be aggressive and not crash, you just need to know what %105 is then back it down to %98 and keep it there.
Mina it would be best for you to show up Saturday and get some practice time and a qualifying heat race in before the Sunday. It really helps get you up to speed and figure out any adjustments that need to be made for the race. Once you've got the hang of the weekend showing up on Sunday isn't a terrible idea and gets you out there to have fun.
