Weight wise, best to ask John. Or do a search on some of the US forums where people have also fitted the Alcons. Don't forget that the Alcons run 365mm/343mm discs which are larger than the AP/PF equivalents.
Caliper wise, I held the AP and Alcons in my hands before fitment, and there seemed to be nothing noticeable between them in terms of weight.
But the Alcons are monoblock and they are crafted/finished veeeery nicely
For fast road/Ring and track days, I honestly don't think you will notice any difference in weight between the APs and Alcons.
