Only the 100dci came with rear disks.
Seems like its a direct fitment the issue isn't with fitment but with the abs sensors but it would seem there the same so you shouldn't have any issue people stuck 172 stuff in 1.2's without abs issues so you shouldn't have any just swopping rear suspension.
There no point though drums are better I wish my Williams had them.
better of staying with drums , the rear disks on 172 1.6 16v and DCI are crap to be honest i dont have any trouble with the drums over heating or anything and the shoes last ages , but if you gonna go for a retro fit they will fit but buy the whole beam make sure it comes with abs sensors and buy a handbrake cable
