RX7 rear axle and brake question

I am thinking of modding a RX7 rear end for the bugeye, but had a question about how the brakes will work out. If I do this, it will add rear disc brakes. Will it work with the stock 3/4" bore master, or with it and a proportioning valve, or will it require some other setup? If I can make it work with the stock master, I will do it.
Also, where would the proportioning valve be placed in the system if it were required?
 
If you are doing this simply to improve braking performance you will go through a lot of effort and expense. From what I have been told, 90% of a Spridgets braking power comes from the front discs. A better grade of front pads would likely improve braking performance. Now if the issue is major HP and twisting/breaking axles then a RX-7 Rear End may be the way to go. It's likely still cheaper to go with a set of competition/hardended axles than going with an RX-7 Rear end. Take a look at
the-mite.com and you can see pics and discussion on how he added an RX-7 rear end to a Spridget with Turbo Miata Drive Train.
 
I want it for the limited slip
