Not familiar with the product "KOOL mat", but to keep the footwells, and passenger compartment cool, we used a double face aluminum insulating mat from Sumit. The Summit techs know wht it is. About $40/roll. Install from dash foreward, under the carpet.

Your LOCAL Track, Pep Boys should sell single faced aluminum padding for about $20/roll. Typically used to insulate insides of vans. Install from dash rearward under carpet.
