I have a 1995 M3, and I usually put the RPM's near 3k then drop the clutch. Depending on how many people I have in my car, the RPM's vary. If the wheels keep spinning, try launching a little lower in the RPM's. MOst people who drive Z28's, do not know how to launch their cars. I think it is b/c there is too much low end torque.
