what's your best launch rpm?

Before I new it, all 4 tires were spinning out and I was starting to drift at an angle. Let off pretty quick but boy, what a rush. These damn cars are bad S..tt
First time I ever did that. I might need some new tires seeing all 4 wheels were spinning.
4K for me is a good launch range. It's all about how you let off the clutch and give gas at the same time. Takes time. I've been driving for 17 years so I got some good experience with launching, even though I don't do it much.

actually if he was turning and on the gas maybe after the launch all four lit up, but not initially.
i launch anywhere from 5-5.5k with a little slip and then let it all out. i've never bogged with this but if i slip it too long my clutch gets mad at me. stupid stocker!

Seriously, the best launch advice, with stock tires, clutch and power, that I've
received, and it worked great, is to hold the RPM's at about 4k, then when
you're ready to go, floor the throttle, and just when the RPM's reach 6k,
let the clutch out fast (but don't just side-step it, especially if you've removed
the restrictor). This gives the turbo some time to spool up as it's accelerating
the engine.
This gave me at least 6 non-bogging, non-clutch burning launces at autocross.
But if you let out the clutch a fraction of a second too late, or too slowly, you
*will* burn it. In my experience, you get to create that wonderful aroma
of melted friction materials only about 6 times per clutch, so be careful.

1.696 and 1.698 on Fri night, previously used (3k miles) stock clutch now in the car. Week prior I was pulling 1.8's, many thanks to TTP_Engineering for adjusting the engagement to my liking. It was grabbing almost at the floor making it nearly impossible to launch.
