Disk Brakes
#1
Are the rear disk brakes interchangeable with the drums? Or would you need a whole different setup. I found a place where I can get rear disk brakes off a 79 or an 83 rx7.
Also I've heard second gens have a better electronic ignition, then the first gen setup. what would I need to convert that. I have both the coils and the igniters off a second gen.

well you need to find a complete axle from a gsl, and the e brake cables. its about 10 bolts and a couple of brake lines

There is a way to convert a drum rear end to a disc rear end without having to replace everything (or so I've been told). You will need the rear calipers and hand brake cables from a 4 wheel disk version ('81 or '82), and the front brake mounting plate from an RX3 (yes, that's right, an RX3!). Apparently the rear disc brakes on an RX7 have the same mounting configuration as the front brakes on an RX3. The rotors may even be the same, but I'm not sure.
You need to strip the rear brakes and backing plate off the RX7, then mount the RX3 front disc mounting plate to the same 4 bolts that held the drum brake assembly onto the axle. You should then be able to mount the RX7 rear calipers and attach the hand brake cables from a full disc rear end. You wil also have to make up some new brake lines (but that's a good idea anyways). This will also require the rear bearing to be removed to getthe old backing plate off, or you'll have to cut off the old backing plate. It's probably a good idea to repalce the bearings anyways while you're in there because we all know how often they wear out.
I saw a completed rear end done this way on an Australian '79 RX7, so it should work in NA as well. I will be converting a rear end that I have as soon as I track down the RX3 mounting plates.
