Huh, interesting! In the wet, I've always!!! run them with lower pressures.

Any recommendations as to how to set them for wet autocrossing?

Jim,

It was an absolute pleasure to meet you in person! I had a blast on the track and I look forward to sharing a track with you again in the future.

I'll vouch for Jon K as he gets more excited about rain on a track than anyone else I know. He also tends to pass everybody in the rain with ease. (Cue OneLap '03 footage from the uber-wet day where Jon was something like 5th overall in a stock EVO.)

Keep in mind that the pressured I gave are cold pressures. Hot, the RA1's should be 3-4 PSI lower than dry, but because there is less pressure buildup because the tires aren't getting as hot, the net result for what you are after once everything reaches steady state is lower than hot.

I have less experience with autocrossing, but I would imagine that running RA1's in the wet you would want a 2-3 PSI lower tire presure than RA1's in the dry because there isn't any time to build up heat and the tire pressures.

I've never done any type of track racing, but like an ass I like to push my crappy civic in inclimate weather. Like everyone else says, it's all about being smooth. Your driving should always be smooth, but you have to take the "smoothness" to a higher level to drive fast on slippery roads.

I feel so awkward typing this, for some reason I feel like an Initial D fanboi.

What do you recommend for camber in the rain? More or less than in the dry?

I'd guess less, as you'll see less roll and compression in the corners.

Confirm?

Go with less, you want as much rubber on the road to get as much grip as possible.

Read: The art of racing in the rain by Garth Stein. It is a great story, tips on racing in the rain, and a cool dog named Enzo.
