Rain days are a lot different then regular trackdays. You don't go fast and its all about being smooth. Not chopping the throttle, being smooth on and off the brakes, and getting your lines up well beforehand. Also, keep in mind that all tracks are different in the rain. Mid Ohio is about worthless and not worth it. Nelson has a fair amount of tracktion, but you can still eat it. I'd imagine PIRC is pretty compareable with how the surface is. As for gear, pretty much what the others day. I got a big blue oversuit last year and that kept me pretty dry in the full rain, but not sure I'd do it again for $30. Maybe if it was black or a cool color (Though, I did stay dry and had a great time)
