So, I've bought the Kart's dlc and +/- 15min after it, I found several bugs.

1. The sound of tires have a strange delay, and it isn't looks real.
2. When I shoot in the kart, the game shows the option "Set up the kart". (I think that this is only for when the kart is upside down)
3. The tires are so fragile, one shoot and it disappears. But when you crashes the kart, nothing happens. And, in my opinion, it's so easy to drive. I belive that drives a kart in real life it's a challenge, but in the game it's soooooo easy.

Sorry by my bad English. :P
