NFS: Pro Street Pagani Zonda Drag or Speed?

I'm just about to buy the Pagani Zonda and I can't decide whether to format it as a Speed car or a Drag car. I have the Shelby GT500 for both at the moment both of which are very good cars however I have noticed I am not winning by as much now as I use to. I don't want it as a Grip car as I already have the Lamborghini Murcielago for that and for my Drift car I have the Corvette C6 which I may upgrade to a different car in the future.|||if i remember correctly i used the zonda for a speed car and the lambo as a drag car.i always had trouble with drifting in this game for some reason but i will have to try the vette and see how that works out.hope this helps.good luck.
