Down hill would be more dangerous no Power to turn the car away from the Cliff.

Did Goodwood not do this ONCE?

If memory serves the soapbox derby race that was meant to be a bit of light humored fun, was hijacked by the F1 boys who showed up with wind tunnel tested carbon fiber designs that flew down and off the road.

What's the largest go-kart tire you can buy?

Edit: looks like about 9" wide slicks.

I wonder if that would provide enough grip for the trip down?

Manual brakes might be interesting though the car would probably be pretty light.

Okay, now I want to build a serious gravity racer. Which I suppose is basically a lay down shifter kart with no engine.

I was just looking for a picture of that to post, you beat me. I remember that from the 1980's. Me and my BMX friends would hold unofficial downhill road races, but then I got older and discovered sport bikes, with motors.
