my car doenst usually spins at start, with or without track. it might spin for a sec and thats it, but this doesnt mean that smth is wrong. ls is a very heavy car i have to agree to that so on slow speeds or from a start its hard for it to show itself but after 15-20 miles you cant compete with it. i'm not talking about the highway speeds. not many cars can beat ls on the 60-100 interval
