On certain 2018-2020 BMW vehicles, (G12, G14, G15), the technician cannot perform brake rotor resurfacing using the ProCut PFM9.2 or X9 brake lathe. The lathe gearbox housing contacts the large-diameter rotor, preventing proper setup.  

New models introduced with brake rotors larger than 374 mm (14.75-inches) require new equipment for service. 

An upgraded package is available from ProCut, including modified gearbox, shortened side plate, extended feed screw, tall tube adapter, and modified 12XX series cutting head silencer.
