How should i launch with the dr's

Easing it out is best. Radial tires don't wrinkle like a bias ply or slick, especially low profile 17" ones, so if you shock them they will just blow off, most of the time. 5k RPM is a good starting point. If you blow the tires off, simply back down to 4500-4800, if you bog, simply raise your revs towards redline Heat up the tires pretty well if the tires are brand new, and take your first pass kinda easy until you're sure the tires are fully burned in heh.
