There can be a benefit to carbon fiber, but I believe it requires heat and pressure(in other words an autoclave). I doubt a Speedster builder would possess an autoclave large enough for a body mold. Heady technology.
Heat/Pressure isn’t required. The same thing can be achieved with vacuum bags and heat lamps. All the pressure/vacuum does is force the resin into the CF cloth fibers. The heat just speeds the curing process.
FWIW, the autoclave method was pioneered here in Utah at Morton-Thiokol for missile tubes. When McLaren built the first CF tub’s for F1, they were cooked here in Utah, as M-T had the only autoclave large enough to fit one. (Nowadays, they’re pretty common.)
