Z4M discs on 335

Hi guys, looking for some performance discs for my 335 and i can get some zimmermann sport drilled discs from germany how ever these are solid discs same as factory design, i would prefer 2 part discs



ive done some digging around and found some OEM zimmermann Z4M 2 part rotor/bell discs exactly what im after to help preven warpeding on track



the discs are 2mm thinner and 3mm smaller in diameter, i would imagine the piston will take up the 2mm but its the 3mm smaller in diameter im not sure about, it will only cause the pads to lose contact over 3mm i would imagine?



Any advice would be great thanks Dan
