I'm trying to figure out the best launching technique for a stock Touring Z on OEM tires on a track. Any suggestions?

 

I'd run your tires around 27 psi to start, and give them a little burnout before you run. Don't go through the water! I would try to launch around 2500-3000 feathering the clutch. If the tires don't hook, lower your tire pressure a little at a time until you get the best results.

 

Thanks. What about the VDC? Should I turn it off?

 

Definitley turn your VDC off when u race it is a huge diffrence since if you shift to fast/hard into 2nd and ur wheels spin a little they will lock and the vdc will cut ur throttle since we have the drive by wire but VDC is great when it comes to the turns saved me a few times
