Well, the autocross was yesterday, and it was a blast! The only annoying thing was that there was a ton of people. I think there were around 175+ cars racing, so it took forever.
I ended up being pretty slow compared to everyone else, but I wasn't expecting much. I think my problem was trying to go too fast and not braking enough before going into the turns.
Also, I can confirm that it's true what people say about getting an oil cooler. I didn't pay attention after my 2 morning runs, but after my 2 afternoon runs, my oil temp gauge was sitting right at 220. I may look into getting one if I continue autocross-ing.
