Did some experimenting with drag slicks yesterday. Significantly easier to control the launch with these and much better 60' and 0-60mph times. Attached is a comparison of 2 of the better street tire launches vs the 2 runs performed with the DR's. Looks like the initial brake boosted rpm's could be increased further and the rate of moving the skinny pedal to the floor could be increased for further improvement.
