It appears to me that your not doing a good enough of a burnout to get the tires hot and sticky. That is why your 60' is horrible. Once you get the car to 60 foot, then 90% of the battle is done. The rest is just shifting fast, and keeping the car straight. I think Mickey Thompson tires require a descent burnout, but not over excessive. Since you have a M6 trans, get the tires in the water, put the car in second, rev it up, dump the clutch, and lightly hold the brakes so the car doesn't move. Once you see smoke in your rear view mirror, your good. You can also call M/T and ask about tire pressure, but 19lbs is a good starting point.

I tried the launch control but seemed to not working :
nanies of, mode 5, first gear engaged, wheels straight, and when I accelerate it stays at 5000 rpm (seems too high for me, is n it ?) and when I launch it spins a little and the engine cut down the power.....
I watch many videos read and read again the process I don t see where I do it wrong. Do you have an Idea?

thanks

Nannies must be on and the accelerator pedal must be all the way to the floor and should stabilize the RPMs after a few seconds....

Learned something new today.

After learning to drive stick decades ago in a Honda 4 cylinder, the thought of trying to do a burnout on purpose in second gear never occurred to me. I've done a second gear burnout on accident after not shifting into first at a stoplight and just giving way too much gas (remember, never had a car with this much torque before..) . I have to say I was laughing at all the smoke the people behind me had to go through. Like I said, that was not on purpose.
