on an m6 ls1 what is a good launch technique (rpm to launch at) My car is pretty much stock besides intake exhaust and a little suspension (sway bars and springs) i have pirrelli nero zeros 275s on an 17 inch wheels. also my car only weighs 3320 pounds (not sure if it makes a difference)

Start at 2000 rpm and work from there. Street tires are hard to launch without spinning.

I have the same setup...someone told me to (at the line) bring the clutch out to right where it starts to engage...then when it turns green, bring the rest of the clutch out and slowly give it gas. I haven't tried it yet, but it seems to be a good technique

when mine was stock the best 60foot i got was a 2.012 . the way i did that is put it at 2 grand and get the clutch right at the release point and ease on the go pedal.

Yesterday at the local track I got the personal best with short time.

The 4 passes I've made, these are my 60' times with street radials.

1.924
1.932
1.960
1.988

I did nice burnout to clean the tires, raised the rpm to 3,000 and let out the clutch little and held until got the green light, release the clutch and gave gas some and went WOT.

Funny thing is, during previous weeks, I always lowered the tire pressure to 22 - 24 PSI (my best was 2.024), but I didn't do it last night, my tire pressure was at 40 PSI, it's weird that I was able to achieve my best short time without messing with the tire pressure.

Gets some slicks, hold the engine on the rev limiter and side step the clutch.
Bring broom and dust pan for diff parts.

Okay, that was bad.
Clutch modulation is the ticket. 2-3000 is good, then like others, press on the gas at the same time you let the clutch out. Lots of practice is the key. You may buy the odd clutch, but you will save the diff and pull good 60's.
