If you found nothing concerning drive wheels (front wheel/rear wheel) on the site then i would imagine that you could use it. I doubt that local clubs would object because it was front wheel drive instead of rear wheel drive, but there might be some problems at larger, more officail events as they probably follow the ROAR regulations more closely.

How does it compare to similar spec rear wheel drive stadium trucks on thew track? I would think that there would be a lack of grip with using front wheel drive, as under acceleration the weight would be shifted to the rear of the vehicle. (although under breaking and sharp turns you may have an advantage). Also, there appears to be very little tread on the front wheels (or is that just the blurry pic?) which cant be good as the wheels would just spin under acceleration.
