I broke down and ordered a set 205/245 16" of Cups from Tirerack today. It was the free radio that did it.

Does anyone have suggestions for hot tire pressures and wheel alignment setup?

I currently run stock suspension with OEM s02's at 36psi hot with a rather tweaked alignment for better balance (front -2.0*, +5.5*, toe out .12", rear -1.5*, 0 toe).

Should I start the same with the Cups or make changes?

 

that's a really strange alignment you have. what I usually recommend is:
-1.2 to -1.5 front camber, as clsoe to +6 caster as possible ($5.5 is even fine), 0 toe.
-2 rear camber and -1/8th toe IN for the rear.

The more negative rear camber you have, especially more so than the front camber, will dial in a bit more understeer in the car.

 

Mike, have you been on the track with that setup? Damn, that's aggressive as hell, and looks like it'd really be a handful. The S2k does not lack a sharp initial turn in at all (IMHO), and does not need toe out like some other cars to get a great turn-in.

In addition, one typically runs toe-in in the rear, to keep the rear where it's supposed to be. . . in the rear. Note also that you typically will get a little toe-out under hard acceleration, not a good thing when you start with zero toe. Also the stock alignment on the S2000 leaves the S2000 pretty predictable under trail braking, I'd be afraid of your rear end dancing too much.

I could be all wrong, though, especially if you've found it to work for you.

I like Schatten's setup.

Gotchya. Damn, if you can handle it more power to you! Gotta have some mad skills.

Edit: I do like the increased front camber though. Should go a long ways toward evening out front tire wear, particularly considering how sticky the Pilots are.

 

Hey frayed, it's not that bad at all. A bunch of people have driven my car on the track. Of course my seventeen year old son keeps telling me that the problems I've been trying to solve are still not solved yet completely. He is right of course but I won't let him know that.

Camber is a compromise. You need to balance several kinds of wear, when turning: the outside edge of the outside tire and the inside edge of the inside tire, when straight and when braking: the inside edges of both tires. Every track is going to change this balance so there is no single correct answer. Also, your degree of aggressiveness, which changes, has a big effect also.

Hey Gil, maybe we can trade cars and see how they compare? I may be able to do some testing and have something particularly tuned for the new tires by then also.

 

Sounds good.

 

Hey mike! I am glad to see you have bit the bullet and gotten some R tires . I hear good things about those tires, but don't know anyone that has used them yet. I look forward to hearing your impressions at Thunderhill.


Are you making any changes to your brakes too? Last time we talked you were worried about over cooking them.

 

Removing the shields helped. Soft suspension may now be an issue with added cornering loading, but if it is really bad I probably will go back to stock tires.

 

Hey Mike, have you driven on the Michelins yet? Any thoughts? I'm curious about people's experience with this tire.
