Hi mate
we tried fitting this Exact setup today on a friends mk2 xr2...
2wd 4pots and rs2000 discs..
discs sit where they should, but the calipers dont want to line up to the discs properly, going to have to take a grinder to the bolt holes and take a few mm off them, will be a trial and error job now, we had to put the old setup back on in the end
something just wasnt right with the angle they made the discs sit at
best thing to do is get hold of a spare hub and trial fit them off the car i think, and keep taking a little shave off the calipers with a grinder...
They WILL go on though, just a little bit of extra effort over the 4wd ones
hope this helps
