Using xr2 discs with metro 4 pots?
Is this possible? I measured between the pads and there is around 21-22mm gap for a disc. So is the 20mm thick xr2 disc going to be too slim?

LMAO you still asking about brakes! I'm assuming your measurement between the pads was when the piston was fully returned into the caliper? If
so, yes they'll fit. You might not get the full use out of your pads though.

Lol, yea sorry!
In doing so I found some useful sites
http://www.blackdiamondperformance.com/brakes_rover_austin.htm
Says the minimum thickness is 19mm but the actual thickness of the disc should be 20.8 so I'm pretty much bang in the middle there.
This site also has a lot of information about disc sizes of various cars

Also, I believe I am right in thinking that the pcd spacing is the same with sierra discs and xr2 discs? They will fit just as the sierras will?

Both vehicles are 4 x 108 PCD, so they'll fit in that sense. Not sure about the hub though. I think both are 63.3mm but you'd best find
out!

By using Google  Just look at owners clubs, people selling alloys etc, they all have this kind of info.
Yes a MK 2 XR2i has the same PCD (4x108) and hub centre bore (63.3mm) as a Sierra.
