I purchased a South African Big Brake kit as part of the group
purchase a few years back. However when I purchased the kit I had a
2WD and now I have a syncro. I ended up installing the big brake kit
on the syncro, apparently the only difference between the syncro kit
and the 2WD kit is the inclusion of spacers for the hubs, and of
course the 2WD kit does not include syncro hubs. I kept my original
syncro hubs, rather than replacing them.

I was placing an order at GoWesty and decided to get some spare rotors
and pads for the brake kit and noticed there is a difference between
rotors for 2WD and 4WD. Apparently on the center, hub area, is larger
for the syncro, does anyone know if the spacers for the syncro kit are
there to account for that difference? I am pretty sure I should be
buying the syncro rotors (my vehicle is a 86 syncro) but I have a tiny
doubt because my big brake kit kit was originally for a 2WD.

Thoughts?
