Re: how to launch
This is how I'd learn if I could. Find an abandoned safe place and use some kind of GPS or data logger and do 0-60 runs changing one thing at a time. Be it air pressures, launch rpms, etc. You'll have all the info you need after a while. I failed with street tires and a wavetrac. If I got out of the hole it would break loose in the upper rpms in first, short shift and break loose again in second. Perhaps a softer suspension would help.
