Just drive the darn thing! Lol
We experience 105 to 115 degrees here in Bakersfield California decert
And also at Button Willow Raceway, along with Willow Springs raceway, and some times is pretty humid.
Sorry, I’m just feeling smarty today, LOL
Bo is right, there are a few cooling shirts and underware to keep you cooler to some degree, and it does make a difference, by lowering the temps a bit
I would try that stuff before I spray anything on my clothes or flesh
The water system, of liquid cooling system seems a little complicated, and as mentioned previously, it’s just another thing to go wrong with. Fast Freddy.
