OK,

So after installing the Bwaits front big brake adapters (it works like a charm) I have 5 lug in the front, and 4 in the rear. so I started welding in the holes where the lug bolts are pressed so that I could redrill to 5 lug 114.3.

I thought to myself, why not try a FD, or FD rotor, and just respace the caliper? The FB/FC/FD all share the same pad set, I think the major difference is the rotor diameter, so other than the mounting points it should work.

Has anybody tried to mock up a FC or FD rear rotor to the FB axles?

If you have tried this before, please post any data you had from it. Getting 5 lugs in the back is easy enough, but I would really like to upgrade the brakes back there at the same time.

I have wondered the same thing. I would think the FC rotors would be relatively easy to adapt to SE axles and calipers. As you stated, the SE/FC/FD all share the same rear pads.
Adapting to the non-SE rear would be a little more involved, but I am sure that a person with decent fabrication skills could accomplish the task.

 

Yeah, I think maybe the FC might be easier, but I just happen to have a complete sets of rear rotors that are almost new for an FD sitting in my shop so being cheap, that awas my first inclination.

I though about mounting the calipers, from an FC or FD but I am not sure if there is any difference performance wise....

Just do "Advanced Search" and look for 2nd gen rear brakes. My description is given in post number 13 of this thread:
