They have a review of the G8 GXP up at edmunds, only one thing worried me. They said that the car had wheelhop during launch. This makes me somewhat nervous but I don't know if this car has the different size half shafts that the Camaro will. Why would they leave that out of an otherwise awesome car?

Just click on the specifications and scroll down to acceleration comments where they talk about the wheel hop.
