Don't know if this fits the arguments going on here, but there is a carbon fiber 1/8 chassis being used, sorta.
A guy in Germany makes aftermarket CF chassis for use in BL conversions of 1/8 buggies. He uses the stock aluminum chassis from the steering rack forward to make use of the front rake... and the rest of the chassis is cut from CF.
It's like a B3 chassis in reverse.
