correct that weight is not an issue on the salt, but torque is. light on the pedal is the way to drive, even sub 200. If youve ever driven on packed snow at speed, you know what im describing. You dont steer, the car floats around. Its an amazing experience. Im actually toying around with building a diesel roadster to get back out there and race again. I really do miss it. Im liking the driver up front idea and the narrowing of the body. I would guess that you could shave your tires of the tread and rounded them, they would look ok, OR, find some O rings that fit on your wheels. Remember, minimal contact patch is speed...I havent forgotten about my offer to you on the rule book info. Still working on it
