Toyota will bring a GT86 TRD Griffon Project to the Goodwood FoS this year. The car is substantially lighter (227 kg!), thanks to CFRP (carbon-fiber-reinforced plastic) and carbon fiber body parts. Glass parts have been replaced by polycarbonate units, which doesn't really make for a downside, as this car is supposed to be a track-optimized tool. While the engine doesn't get any changes, the car gets a mechanical diff and shorter final gear ration, new cooling kit, coilovers and neat monoblock calipers, better brake pads.

Would anyone buy super-expensive body panels made from CF or CFRP if they actually offered them?

Sauce.
