LOL! Yes, they are the original wheels, with the web of the casting painted black..... Stock wheels on that vehicle..
Wow, that black really brings out the rounded casting around the lug nuts (as opposed to the flat casting on gtb/gts models). I had never noticed that difference in the wheels between the models. What year did the GT4 switch to those wheels from the orig "Dino" wheels? Or was there factory wheel options?
308 GT4s were always available with standard Cromodora 6.5X14 wheels or the optional 7X14 Campagnolo wheels. The Campagnolos are seen above with non-standard black paint. Both wheels had "Dino" badges until it was decided by dealers and the factory to replace them with Ferrari caps.
