There is a reason we tell noobs to put 40psi in their tires for their first autocross. Some people in my region have seen it happen first hand.
It's all fun and games until you have to crawl out of your own car and get help flipping it back over.
Also, I notice a lot of noobs (myself included, when I was in my noob stage) and even some more experienced people like to drop pressures and say that the car feels faster/better/insert improvement here/etc. What is actually happening is they are lowering the effective damping rate (yes, your tire sidewall acts as a damper in a way and is part of the overall suspension picture) of the tire, which makes it feel easier to drive. In general, lowering tire pressure actually reduces total grip available unless your starting pressure was so high that the tire was becoming a torus. See here:
