I use a DIY race chiller system from a company called ultra chiller. https://www.facebook.com/UltraChillerI've used it on 115'F days in my lemons car at Thunderhill for stints up to 90 minutes and been cool and comfortable the entire time. The systems uses a marine type bilge pump in a cooler full of ice water to pump ice water through a t-shirt with tubing sewn into it. The tubing/shirt goes under your race suit. With the system on its more comfortable in the car than out of it! -Jon
