The weight difference between the GT4 steel brakes and GT4 PCCBs is 17kg.
They say as a rule of thumb that weight reduction in unsprung mass counts double so yes, it's quite significant. I wish Porsche offered a resurfacing service or trade-in program for the rotors, then I'd spec ceramics in a heartbeat.
Thanks for the info. I measured a 396mm CCB disc vs a 389mm cast iron disc from another manufacturer in the past and the weight difference was around 7kg. Taking into account other differences in the setup and less weight save for the rear discs, then its hard to question the 17kg. Like you, they'd be one of the first options I would spec.They say as a rule of thumb that weight reduction in unsprung mass counts double so yes, it's quite significant.
