In the heat of a bitter track battle, keeping your car cool is critical. Reliable coolant temperatures can be the difference between setting a new track record and watching an engine crack under pressure. These high-stakes scenarios are all too familiar for the Hyundai, Kia, and Genesis veterans over at KDM Tuners. For over a decade, Josh Sadler and his team have been campaigning vehicles from the Korean conglomerate in racing series across the country, knowing firsthand the importance of maintaining steady coolant temps to stay in the fight. The 2026 GRIDLIFE season was no different, and the KDM Tuners team turned to Koyorad to handle thermal management on the #66 Hyundai Elantra N. Competing in the Street class of the Track Battle series, driver Will Drees showcased just how capable this platform is—especially with Koyorad’s all-aluminum performance radiator keeping engine temperatures in check. To see how well this unit stood up to a full season of grassroots time attack, we caught up with Josh at KDM Tuners.
