Well i was told to rev to about 1500-2000 u dont want to go too high cause that will just cause ALOT of wheel spin.

Unless you have $ for new clutches on a regular basis, don't slip it even though it does work. Try feathering it off the line from idle. It's a trial and error thing but you'll get it.

4k+streeties=MASSIVE wheel spin.

On streeties, try 1500 and slip it just a hair-dumping will also cause too much spin, plus the stock clutch and rear dont like dumpage much . I've got 23k miles on mine and ohh, about 75 passes on DR's while slipping the clutch, and it's holding up fine. Just dont over-slip and smoke it and you'll be aight.

On DR's, I do 3500+/- and slip the clutch...it's made for a few low 1.9 60's so far.

Also- carry it on up to 6k (or as close as you can get to it) before you shift...when I first got my car I was too chicken to go over 5500 when racing, but you wouldnt believe what a difference the extra 500 rpms has made.

Depends on your tires. If you have Nittos or equivalent..1500-2000 will cause you to seriously bog. If you have street tires...4000 will just spin. Use those numbers and find the happy medium. It does take practice. Rarely will you see a 1st timer do a flawless launch. Slipping the clutch will greatly reduce its life but if done right can net good 60ft times. Good luck and remember....you'll get the hang of it

My best experience is revving to 3k or so and easin the clutch out. Gets you moving off the line a little better. At least for me. When I did 1500-2k launches I was feeling like it was bogging. You want to get it moving first thing. Its not good for your clutch but as long as you dont hot lap it it will be fine. If you were to directly ask me I would say hold it at 3k and slip the clutch slowly then WOT. If that dont work then just adjust the rpms your launching at to lower like 2k or 2500.

Caution...install subframe connectors prior to sticky tires.

well, get used to high 1.9's and for the most part 2.2+ 60's with the M6, unless you're ready to get a clutch, a rear, and some slicks. they generally dont like stoppie racin in stock form.

now, get ya those parts along with some sub's and suspension stuff, start launchin @ 5.5k and get ready to cut low 1.5 60's w/ some minor motor work.

To eliminate Wheelhop, LCA will do the trick. SFC helps little but LCA will plant wheels on the ground.

LCAs coupled with brackets will do even a better job

Your F-body will experience some serious flexing when launching off the line. The constant flexing will cause squeeks and rattles in your car. Once that happens you'll hate it. SFCs will allow your chasis to be a lot more rigid and stops the constant flexing. You can definitely feel the difference.
