You guys that think its ok to run antifreeze please stay home and garage race over the internet.If any of you guys ever had a car that had enough power to spin the wheels you would understand the guy in the 8 second car behind you would probly nut you if you spilled antifreeze in his lane. Then the track crew would be next in line and then every racer that has to wait half hour or more to clean up after your junk. Reson water over antifreeze is water will evaporate on a hot track. Leak a mist of antifreeze its not easy to see but it will be like a ice covered road.
