This is actually the single most important decision, and I have not made up my mind yet. I need to think about it at length, because handling of the car will depend on it greatly.
The original Budget Bugatti Project kept a "period" front end with old fashion leaf springs and friction shock absorbers, for the sake of realism and simplicity. It has it's charm, and would be easier to build. The chassis has just two rails, and we could probably use Hot Rod parts:
BUT since McPherson came up with his strut, and especially since the development of the Double Wishbone Suspension which allowed control of camber, we know we can do a lot better, and have built in adjustments to tune the handling of the car to boot.
I was at the Barber Track the other day, and shot a bunch of pictures of all kinds of variations on the double wish bone concept, with external and internal spring. Looking for something we can actually build with tubing and a welder.
The simple Colin Chapman Lotus design can't be beat:
I remember a friend working on his Lotus 7 back in my engineering school mechanic shop in 1965, and it was already exactly the same basic design :
But a more elaborate tubing frame has to be built to attach the struts, which also provides more rigidity. The original Chapman chassis seems a good place to start:
The back would have to be totally modified for the single rear wheel, but the front could actually remain pretty close, just adding re-enforcements to attach the V Twin.
