Glad to hear you had fun -- regarding tires, you almost certainly built too much pressure while on track.
The best way to prevent that from happening is to come into the pit area from the track once you feel them getting greasy to immediately bleed off hot pressure, then go back out. You likely only need to do this once per day if conditions don't change dramatically.

fwiw, I did a track weekend at NJMP. My 99 boxster has the stock 2.5L with a third radiator, 160 thermostat and a new waterpump and the coolant temp would go to 102c and stay there. This is basically me being at WOT the whole lap (not much power in this car).
I think the third radiator is a good idea. It weighs practically nothing, its cheap, and it helps.
Now if I could keep the thing from smoking halfway around the track from the AOS, I'd be in business.

You 102C sounds about perfect. I can't think that a 3rd radiator would hurt anything other than the added weight, and seems like a good idea, like the low-temp tstat is as well.

Quadcammer, I track both the Boxster S and the C4S you see in my sig, AOS smoke comes from start up after a hard run, and only for a second or 2. I have NEVER had smoke during a hot lap. There should be NO smoke while on track. If your Boxster S smokes while running on the track, there is something else wrong. Modifying the AOS won't fix it.

Slakker, I was always under the impression if it got hot enough for that light to come on, you were pretty much at the point where damage was happening. With the thought of cracked heads and such I would poop my pants if I saw that light rear its ugly little head. I'm sure I could be being overly cautious, but with how expensive it is for new engines for these cars I guess I'm just geared to err more on the side of caution.
