Pagid ref numbers for AP and standard rears

[TMAQ]

In the process of changing my pads all-round and replacing my front AP discs with PF ones (PF discs ref# 356.32.0054.03/04). I have a standard setup on the rear and have the AP kit on the front, the AP kit I have is CP5575-1004.

Been shopping around for decent prices, however need a hand to clarify a few things…

what is the pagid ref number for this AP kit, E1903 I think? The AP website references CP5070D54 for pads but a few companys I have emailed say Pagid don’t exist for the AP kit I have, even though I have Pagid on there at the moment and a fair few of you guys do. The companys that do the pagid, dont do the rs14s.

Regarding the new PF discs, 99% certain they should mount the AP bell’s I currently have?

The Pagid pad reference for the standard rears, E2685?

thanks
