At race countdown, hold the accelerator down so the revcounter needle hits the 12 o'clock position. Then quickly step through the gears to about 4th [or 5th] while keeping the needle at approx 12 o'clock. This requires a balancing act between the needle and the accelerator button. Now as long as you have L2+R2 held down as the countdown finishes you will be propelled forward at that gear without suffering wheelspin!

Rocket Start with neGcon
I believe I've executed the Rocket Start with a neGcon, except there are no L2 or R2 buttons, so I didn't hold them.
It's excacly as the Rocket Start by IcemanUK, but here it is for completeness' sake: Quickly step through the gears to 4 or 5, then accelerate to about 12 o'clock position (around 6000 rpm for me). Don't worry about the L2+R2, the neGcon doesn't seem to need it.
Note: neGcon is an analog racing controller from namco.
