gentlemen...while in St. Louis for the CAA event...I drove in 98 degree heat, in traffic to the track...within a half hour or so, I was doing a lap on the track...ended up running 3 laps. I knew my power would be down..since I had driven around earlier, before leaving for the track...the power was down some due to heat soak..the heat index was 110 degrees...the track surface was very hot. My little roadster did fine the whole time...never over heated, never let me down. My times could have been a little better had I chose to let some air out of the tires, but not knowing whether I could find a place to air up, I choose to leave them alone and slide a little bit...that car proved to me that day it can handle just about anything...no need to worry about the heat...she can take it...my temp needle never went passed the middle mark more than a needle width the whole time.
