Great info, thank you sir. I had read that shifting at 6k is best, and feels better on the street, nice to get empirical data too.

Are you using the launch control? I have a 2013, so no LC. Mine doesn't seem to launch very hard brake torquing, with minimal if any wheelspin... I wonder if it would work better with DSC off...

All my runs where sport + shifter in sport and Manual shifting. I shifted the car at 5.8k I tried auto shift and redline shift and the car is about .3-.4 faster when manual shifted. The key is to shift early as our cars run out of has after 6k rpm.
