a water box is a small channel of water that you drive through to make the slicks wet so you can easily do a burnout to heat them up good.
the guy pointed me to the dry lane with no water, so i tried the only thing i could, since slicks need to be very warm to work properly...pull the ebrake and do a burnout which didnt work so well, because slicks get decent traction (even cold) so all i did was burnout for a very short distance and drag the back tires skidding along locked
so yes, i was very disappointed in my 60', but next time i go, i will have actual drag slicks, not road race slicks and i will make the guy let me get in the waterbox.
