Default Launching 5-speed

I'm about to race my 06 GT tonight. it's mostly stock, and it's a 5-speed. I was wondering if anyone could tell me the best way to launch it. i've ran it once before and revved it to 2000 and dumped the clutch, i ran a 9.1 in the 1/8th (there's no 1/4 strips near me). i'm pretty sure i could get it into mid to high 8's cause i spun off the line and spun through every gear. if it helps i have 235/45/18 tires all around (stock bfg's) thanks!

Don't do that!

You need to raise your RPM's (to prevent bogging)and feather the clutch with a quick-lift to minimizewheelspin (no drops). It is counter-intuitive to work your clutch that way, but you'll get the hang of it with practice. If you're spinning through every gear, then you need to roll into the throttle with each shift. Wheelspin may look/sound impressive, but it hurts your ET (and a low ETis what really matters at the track).

Raise your front tire pressure to 35-40lbs & lower the rear tires to 20-25lbs.This will help weight transfer.Also pull your tire & jack out of the trunk along with everything else in there.It will only take 5min to do.Lastly run your car with an 1/8th tank of gas.This will optimize weight savings!Launch your car around 1800 rpms with the radials and tire pressure set to where I told you.It should be about right.Let us know how ya did!

ok, thanks for the advice. i already planned on running it on 1/8th of a tank. i gotta 1/4 now and by the time i get there i should be at an 1/8th. and also thanks for letting me know the tire pressures, i forgot to mention i was lowering the rears. i'm planning on doing about 3 runs or so, i'll post the details of my run: 1/8th time, 60', r/t (i'm still working on it, last time was .20, pretty good i think for my 1st launch in the car), etc. hopefully ya'll can give me more tips after seeing the times. thanks again : )
