when ever i race my friend i smash on the gas when the light turns green i lose a couple of second because i can't get good taction. to save time what should i do?

 

ok i am assuming u got a cl-s, so

-turn vsa off
-dont get up on it too much, nothing over a 2k rpm launch or you michelins will light up
-a few moments after you let it loode just go WOT

the stock tires suck, if you got $$$ buy some toyos or nittos
