Down in Calclub (l.a. region) the STS crowd got together a while ago and
figured out the whole water sprayer thing on the azeni'. I think the ideal
temp was decided to be about 130-135 and all the top STS contenders spray
their tires down after *every* run. I think they wet them more than the r-
tire guys. I haven't noticed mine overheating but my car is also 2300# and
has that camber friendly double wishbone thing that might help. Or its
driving style.
