I have a 91 na with 4 piston front calipers, and single piston rears. Is it possible to put dual piston rears on the back... I guess I should ask if they even made them on back. And would it matter if I did?

Also I was removing the rear calipers and ended up having to drill out one of the 2 screws holding the rotor on, and I think I hit the threads for the screw in the hub. Do I need the screws (both of them), and if so anyone wanna tell me how much I can find a hub for if I can't re-tap the screw hole.

Also, is the rear steer bushing the one bolt in the hub that does not have a nut on it also? And should I remove the rear steer ability?

I am sorry I got off topic, anyone with insite please hit me up, this is my first Rx-7 and so far I have done everything right I hope and the last thing I wanna do is screw up now.

Anyone wanting details on work done so far, just ask I am eager to share.

The 4-pot front caliper system has single pot calipers on the rear that are different from the single-pot calipers in a base car. That's to accomodate the thicker vented rotors. I have never heard of OEM 2-pot calipers on an RX-7.

Thanx Its one less question I have about the car.

I am rebuilding everything as I go, and was just shocked to see 4 pot in front and only 1 pot in back. But now I know. I can move on to other things.

Once again Thank you

you really wouldn't notice a difference (except for ebraking) with 2-pot rears. since all of your stopping power is at the front.

And if you actually managed to increase the braking power to the rear, you'd need to change the bias, otherwise the car would be unstable during braking... at least in theory... you probably couldn't increase the actual braking power by much.

I'm curious what it would take to swap my brakes to 4-piston front, and vented rear rotors...

damn base models

there are several write ups on it

I want to thank everyone who replied, I have posted many ?'s today and I want to thank everyone who has helped me out. Once I can figure out how to downsize my photos I will start posting for those who are interested in what work I have done thus far.

Thank you

2 piston rears are a waste. The best things you can do for your braking system are stainless brake lines and sticky tires

you dont need those 2 screws on each rotor as your wheel will hold the rotors down, so dont even worry about messing up the threads when you drilled it out... dont even need to worry about putting them on.

After some digging and calling around I got that impression since most people told me they don't even bother with them when they replace brakes... all I can say is THANK GOD!!!! one more part I don't need to buy
