^^^^Is that Chris Aniello I see posting??? Those numbers look familiar..lol. I only run on street tires and don't ever hit the water box, just a strong scrubbing of the tires. TC off, drop it into 1st gear and hold revs at 1800-1900 RPM and roll into the throttle. Best 60' so far is a 1.766 on Hankook Ventus evo110s 285/35 at 30 PSI on both rears. But I will agree with Les on this one, there is no better way to improve than practice practice practice.
