I have the motor set up for drags now and the track is a new 9811 camo speed track with 1/2 inch lugs and I'm using 9" extrovert drivers with an anti stab wheel kit. I only used the proaction rear skid because the old skid was shot and I had the proaction laying around. I will have to suck it down somehow. I have a place on the lake and will more than likely just use it to play in a straight line. Any idea how long of studs I can get away with, with the proaction in her, the clearance doesn't look like much? hman
