These are 120Y or 1200 coupe hubs, Sigma discs and calipers.

thanks sidedraught are they the sigma ones?

bert are all 1200 hubs the same? ie sedan coupe wagon) an do i need to look for a certain year like the 120y hubs??

1200 sedans and wagons used drum brakes,only the 1200 coupe had disks and look like what sidedraft has just posted.
You need the disc type hub so you can bolt a rotor to it.

anybody though of using bluebird rear disks? they are deep and go straight over the 1000 hub.

pics all the way...

matto never heard of the bluebird on the 1000
but i kno they go strait into the vanette with a spacer

I was thinking about using some S13 rotors, but i'm not entirely sure what it will take to do it. Can't you use S13 rotors on a 1200 hub? Sonata rotor are a good option, do they fi t on a 1200 hub?

The Sonata rotor is set up as a "floating" unit.It uses the Datsun hub wheel studs to locate on the outside of the hub(which sits inside the rotor hub)and also widens the front track by the thickness of the inner face of the sonata rotor.
You need to use 1000 or 1200 drum brake hubs unless you want to machine other hubs to fit inside.
