Hi All Are there any decent disc & pad upgrades available for a W219 350 CDi? I had all discs and pads replaced last year and the pads now need replacing again. I average about 40k a year so want some stoppers that can handle a lot of motorway and A road use. I've seen some Black Diamond and MTEC discs, but the Black Diamond only list for a CLS 320 CDi - specs all look the same but can anyone confirm the 350cdi discs are the same as a 320cdi disc..? Anyone got any ideas for brake upgrades for road use ?
