I have an '06 MKV with the upgraded tire package from the Dealer. And yes I get wheel hop, massive amounts of wheel hop, wheel hop so bad it makes you feel like your teeth are going to fall right out of your head. But it happens with the traction control. You really should be launching that hard anyway. The key to a good launch is to find the sweet spot between the lag and the spin. I'm all for looking cool and burning out, but I almost feel like I am doing to car an injustice when I hop the wheels. You basically are dragging the back end of the car for the first 60 feet.
I don't think there is anything wrong with your car, since anybody with a lead foot can make the wheels hop in these cars. I have never had the "stock" rims and tires on the car even though I have them so I wouldn't be able to tell you either way with that.
Find the sweet spot and the wheel hop disappears.
Hope that helps.
