But if you use warmers you can see the change imediately. In only one or two laps you'll know if your change was for the good or not.

As far as what temps to use; I base it on what the outside temp and the track temps are. when the tires are nice and warm the will hold that temp rather well if its a warm or hot day. If it's cold outside, I set the warmers a bit higher to compensate for the heat the will lose while your waiting on the last guy to get to the line. On a hot day I set to about 120f and when its cold I set to about 135f or 140f.
