Lighter rolling stock is also huge. Our cars come with 55 lbs hunks of metal in the rear, most performance cars are in the 30-35 lbs mark.

The 19" size is great for handling, but horrible for acceleration in such a low torque vehicle. Also, BMW ESP is much less intrusive and their ECUs don't pull timing as harshly as the Crossfire. The extra 40 HP and lighter weigt help as well. Less shifting and a smoother shifting trans add to it as well.

In Drag Racing it's not just the power to weight ratio that matters, some cars are set up better to put the power to the ground.

A better comparison would be from a roll with the TVT250 kit of course...
