Lol i wish it was that easy on a stick shiftJust put it in S and floor it, don't use the paddle shifters. I have had mixed results on launching at different RPMs myself so you just have to play around and see what works best.
You always search that ragged edge between hooking on stock tires and breaking them loose. TC will affect your trap speed more than likely. Whether or not it affects your ET I haven't had a chance to find out yet. Good luck.I have had my best launches with TC on, when it's off it just a tire burning fest haha. With TC on its a mixed bag, sometimes I can get a good launch other times it's a 5 sec 0-60, very weird. With better tires though that would be a different story. Track also makes a difference.
I have read somewhere that 1k~ launch has worked well.
