The most common statement from a racer who just purchased a driver cooling system is "Why didn't I get this sooner?" Ultimately, the best sales person for a driver cooling system is the racer parked next to you in the paddock. We encourage you to walk over and ask the famous racer question "Is it worth it?" The answer is not just a "yes" but "I should have gotten it sooner" or "I'd never drive without it." With only a 2% loss in hydration, racer reaction times alone can be reduced by as much as 20%. Racer driver cooling systems help you keep your cool so you can focus on driving and achieve the improvements you strive for. This is the easiest way to correct the "drift" you see after 15 minutes in the race car. DiscoveryParts carries the best driver cooling systems from ChillOut Systems, CoolShirt and Fast to keep the fastest racers up front.
