The one thing that really gets to me about the 2 is the lack of input from the motor. I'm sure the AWR motor mount would fix that right up but I'm trying to stay legal for H stock autocross. I was wondering if filling the stock mount with urethane would be against the rules? I'm pretty sure it would fall under this, "If a modification is not specifically authorized in this or previous sections of these Rules it is not allowed." But I figured I would ask people that knew more than I do.
