S02 p.s.i. for autocross
I have my second autocross coming up on Sunday and I am curious about tire pressures. Many an autocross guide suggests 40 p.s.i. (which I ran last time with what I consider decent results for a first-timer) but I assume Honda recommends 32 p.s.i. for a reason. I am doing autocross to get a feel for the road-going stock setup, more than anything else, so R-compound tires are not an issue. That being said, I would still like to be competitive as possible. Any input would be appreciated.

Just run 32 to 36. Tire pressures don't matter that much when you are novice anway. Just concentrate on the driving... not the fooling around with the air guage.
FWIW, I run 34 on the street and I noticed a dramatic loss in grip going up to 37.

He may be right about the higher pressures up front. I never got the chance to push those bicycle wheels we have up front before I switched to R-comps.
I do know that the rears like 32-34.
Yeah, I'll be there as always.

Are you guys talking hot or cold? (Or does it not matter in the autox world, because the tires don't get hot?)
33 rear and 36-37 front (COLD)

This sounds logical and I am looking forward to having a go at it as the weather is supposed to be great. There will be several S2000s running OEM rubber so it should be a pretty level playing field. Of course, then there are those damn Kumhos messing up everything. Thanks all.

When I do run the S-02's I typically shoot for 37 up front and 35 in the rears to start off with. But I also mark the tires with paint to see if they roll at all then adjust the pressure as needed. It takes a little while for the stock tires to heat up, not as fast as R compounds but they do heat up.

Anyone have recommendations for 2004+ RE050's? I ran last weekend with 36 front, 34 rear and was plowing like a farmer. My technique probably had something to do with it (didn't brake like I should have in some tighter corners), and the event was strangely shut down before I got a chance to readjust pressures. I think I will start with 35's all around this time and maybe even decrease the fronts if I need a little more rotation.
BTW, in the 2 autoxes I've participated in, I've not spun out once, although I got close once. I'm guessing it's a combination of not pushing hard enough and the 04 geometry.
