I have brand new stock good years on and i still spin, I know spinning is bad but your in a FWD,to get a good launch from a dead stop you have to spin a lil or you bog out bad at the the start..
this is my slow ass video(05 impala), just after i seafoamed.was on a road that had a light incline at the top of 1st gear-start of 2nd gear,reason why it slows down so much in 2nd gear. started 25% throttle till stopped spinning then punched it, If i launched it harder I could of done better...
