Does anyone know why the 612 has 18" wheels at the front and 19" wheels at rear? Also I drove 2 360 F1's, a LHD 360 Modena (2000) and RHD 360 Spider (2002). On the LHD Modena when it was in reverse I could pull the right paddle and it would go straight into 1st gear. When I tried that on the RHD Spider it wouldn't work. I had to select neutral then select 1st gear. Does anyone know why they are differnet or is it possible there was a fault on the LHD car.
