Here's some video of Dave Mirra taking some get-to-know-you laps at Southern California's Pala Raceway in the new Subaru WRX STI rallycross car that he'll drive in X Games 16 tomorrow. Josh already gave you full technical details on this car, which makes somewhere between 550 and 575 horsepower.

After the jump, there's a video from Vermont Sports Cars, the outfit in Vermont that built this car, along with every other Impreza rally car Mirra and Travis Pastrana have raced.
