as for burnouts and street tires for racing:

I've tried many diff ways at the track for launching on street tires. This method turned the best results, with best traction:

Roll throgh the waterbox, then pull up on E-brake, and then rev up motor, slip out clutch until you start spinning tires. As soon as the tires start to spin, i let off the E-brake, and ride out the tire spin for about 2 seconds. This produces no big tire smoke, cleans off the tires nicely, puts a little bit of heat into the tires, and gives a nice, clean , fresh layer of rubber to grip the track with. Street tires, or ANY tire for that matter NEEDS to be at least cleaned off and heated up slightly. Even a small layer of dirt and debris from rolling through the staging lanes is enough to not grip as well off the line. In no way, do you want to smoke up street tires at the dragstrip though..If its a cool day, you need to heat them up for another second or two..if its really hot, then less needed..The most important thing to remember, is that you NEED a nice clean layer of tire rubber, to really grip the track good. This just comes from experience on my part anyway..
