after reading all the post, the only way to eliminate antifreeze would be upto the track owners. don't know what the percentage of turn aways would be, but they would be losing cash. i myself use antifreeze, street ride. i go out 3-4 times a year, switching it out is a pain. member dap stated he uses evans coolant, going to call them & see if it's easier to clean up. like other members on here, i have some serious coin invested & don't want to cause someone else or myself any problems. we are all taking a risk driving over 130, i see the anti antifreeze posters point. everyone stay safe, seeya.
