Pavement. 4 radius rods on the front and a brake on the RF. Longer radius rods on the rear. Panhard par on the rear. Inboard LR shock to get the tire in closer. Engine lower in the chassis. Not sure when Beast switched the laydown radiators from above the axle to below. The one in this car is above the axle like a dirt midget.

The wing mounts throw a cog in the works, but I believe this is the car he ran on pavement.
