I need some advice from all of you drag strip experts, especially regarding the IS-F.

I have a challenge going with a buddy of mine who has an E92 M3. Challenged him to a drag race and some track laps. I wondering if anyone can provide some tips.

Such as Sport mode or Normal or snow?
Auto or Manual?
Stomp on the gas, or a half way then stomp?
Let up a bit on the gas during gear changes?
Full VDC on or Full VDC off or just the half way off and let it kick in after 40 kph?
Does doing a burn out really help? (Oh my poor tires)
AC on or off?
Turn on recir air?
Music on or off? Does it matter if I am listening to Queen or Floyd?
What tire pressure?

Any advice would be appreciated.

everything off. lights, a/c, seat heaters, heated mirrors, everything.
maybe a tiny burnout will help.....big burnouts only help drag radials as they need lots of temp.
traction control off.
sport mode.
manual mode.
take your spare tire/jack out.
keep a clean car, dont keep random crap in it.
windows and sunroof closed.
when u go to drag. launch the car. dont just go from brake to gas.
hold the brake with one foot (hard) build up revs, prob 1500-2000 or as much as u can without the back tires breaking loose.
when the light goes green take your foot off the brake but dont just pin it. go from launch position to about half throttle until the tires grip, THEN pin it....

shift from 1-2 at about 6400, shift from 2-3, 3-4 at about 6. you should be done the 1/4 mile by then

AC turns off automatically if you floor it anyway's, but yes do the above and you should do fine. Depending on the type of "tree" your track is using, you want to launch as close to the last yellow light coming on as possible. So Red, yellow, yellow, yellow, go!!!

But don't go too early, or you blew it.
Good luck.

i would heat them up alil nice lil burn out. not to much.but leave traction control on if you cant handle it if it goes side ways, if it were to happen. if you can handle it let it rip i heat my tiers up alil, like get them sticky. ease into it then floor it and let the beeps help you shift.def sport mode and in manual mode if a strait line paddes are ok to use. track use the shifter. but make sure everythings off like power wise

RE

I don't really know much about drag racing and this is just a theroy I made so you can disregard what I'm saying. Basically all I'm saying is to use the clutch instead of the brake so you can have higher RPM's/be in the peak TQ range which helps your car launch better. If im wrong please correct me. Also, do a small burnout because it gets the crap off your tires and heats them up/wears them a bit.

thats all fine and dandy except that what you just described applies to a car with a manual transmission only.

IS F has 8 speed sequential automatic.

As far as I know everything u said is correct but can you please clarify about shifting at 6000 rpm? y is that and r u sure it's the best way to do it?? I would've thought 6400 as well

That really makes no sense to short shift at 6000rpm in any gear at the drag strip. Shift as close to the rev limiter as possible between each shift. The timing takes some practice as you have to do the shift after the alarm but before the limiter hits. Good luck!
