Wait so you do not turn VDC off when you go down the track? It is a traction control system plus; not only does it control the throttle, but it controls the brakes. It is made to keep drivers from killing themselves on the streets. It doesn't turn off "positraction" you have an LSD the computer does not control that. If your trying to race with it that is one of your problems (though you wouldn't be suffering from wheel hop). How wide are your tires? You have IRS welcome to the world of wheel hop. Do you want the car to be a drag car that launches well, a car that is well balanced, or a car just set-up for handling? Because your suspension set-up needs to be built along one of those lines. One thing is invest in some lightweight 16s or 17s that are wide enough to fit some decent size DRs on (265 or 275 or so).


I would recommend before doing anything to a car know more about it. Your lucky you haven't destroyed your G35C yet. Take time and research; get to know your car before you modify it or attempt to race it.
