Bill - I used the Camaro cables. Front/rear bias - good question--- Car's braking feels good, but I've not tested a panic stop and don't even know what position the bias valve is in. I'll probably check it out this weekend. Note that I have Wilwood 11.75 front rotors with their dynalite 4-pot calipers up front and a 15/16" master cylinder.

The rx7 rear from the turbo mounting holes are 6 inches apart. I didnt have my caliper so thats with a tape measure, so I may be off 1/16. I think the turbo rx7 had vented rears and the NA one had solid rotors. It would be nice to start a sticky or another thread with listings of calipers that have built in parking brakes that list the rotor size and thickness they go with and the piston size. It would be a nice little database to have.

Looks good! Are those newer Mustang calipers? We had a Mustang Cobra that had very good brakes, 13" front rotors and I believe 11.5" rears!

That is good to know, sounds like your fronts are similar to mine. I still have the CB B master cylinder and a residual pressure valve on the front. I supect that I may have to go to a larger master cylinder though. However I wanted make a decision on the rears and get them installed first to see how the "pedal feel" works out.

I've been doing some more research and noticed that the auto-makers usually build in and addtional 5-10% front bias. Mainly for safety concerns to help prevent early rear lock-up in wet weather I suppose. If the car is driven in wet weather it would make sense to either go a little smaller on the rears and/or have an in the car adjustable bias valve.

They are indeed from a mid '90's Mustang - non-vented 10.5" dia rotors.
