    Why does GT4 cars have such small rear wings?

      if they had bigger wings they would have similar downforce to the gt3 cars. Which if you do that, what’s the point. You need a speed seperation.

      They’re actually VERY large in person. The span is approximately equal to the car width (and some of the GT4 cars are very wide) and the longitudinal length is bigger than just about any street car’s wing.

    You said continental developed a tire for two cars, but that isn’t true. The tires continental used for dry racing were dp compound tires. Those tires never had a thought of a p2 car in mind when they were made and designed.

      Yes, I certainly could have said that more clearly, couldn’t I? The point stands that the tire was being forced to work for two different types of cars, which isn’t the case anymore, but I wish I had said it the way you did here! Thanks for listening and for the feedback.

        Thanks for the clarification, and I’m happy to listen as long as you guys pump out quality product.

    We had reports from the Dunlop tire test at Sebring late last year that the p2 cars from dallara, ligier and oreca running lap times in the 1:47-48 range. Do you think the conti shod p2/dpi cars will run the same range. And if they do, how soon would conti make an attempt to go to Le Mans?

    For this weeks show i’d like to post two questions:

    1. With the Intercontinental GT Challenge coming to the US this year, will Acura and Cadillac take on the fight to the established GT3 manufacturers?

    2. I know the sportscar split is gone now, but I really don’t understand why GRAND-AM did not go the GT only route with GT1/GT as the top class considering the success this format had in over here in Europe. Was it just an ego thing of having a “Prototype” top class?
    Daytona really faded away in international relevance during the DP era

    John and Ryan, great show as usual. After one of IMSA’s best BoPs ever in GTD, why are we seeing so many changes pre-Sebring test?

    Concerning the #75 SunEnergy1 GTD entry. What will the non enduro line up be? Will Habul and Said do different rounds with Vautier?
