street tires at the track - any tips?

A tip not many people know.Find out if your track has a concrete,or pavement launchpad.Fine out,then,find a similar spot.THEN,LAY WATER DOWN.Launch the car ,as if yoh would on the track.If this is truly a new combo,this will show with tire speed(slowly), how the car will work with the new mill.Sounds far fetched,but it works.....
