This then gives a vertical plane to which you can bolt the belts.

I wouldn't advise attaching the belts to the frame. Our thoughts are that if an accident were to occur if the body separated from the frame the occupants would become trapped in between the frame and bodywork. Not a very nice scenario.

We left the bolts holding the belts to the steel angle so they can pivot on the bolts. All hardware is grade 8 with nylon locking nuts. Yeah, I know grade 8 bolts.... Other things will structurally fail before the bolts do.

By the way the wood floor of the speedster is 2 pieces of 3/4 inch plywood sandwiched together using screws and a liberal amount of glue. It is held onto the frame using 8 7/16 elevator bolts.

As someone else pointed out, tipping over is not the conceren, these speedsters have a fairly wide track and are very stable in turns. It's much more of a concern driving in an open vehicle and not wanting to get thrown out.

THAT would be a bad thing............

Oh, and the lean action in the turns is more to avoid mud than it is anything else.
