    RX-7 4 piston caliper adapting bracket

    I am starting a group buy for the caliper adaption bracket for the RX-7 4 piston caliper. I will provide the bracket for the caliper, and you can do the rest. If you would like me to source all the parts for you pm me separate of this GB. What is needed in total is shown below. I would like to keep this organized so if you post in the gb on r3v, or e30tech, do not post in this one. start a list. I will have prices for the bracket tomorrow.

    89-91 rx-7 (turbo II) calipers
    91-93 corrado g60 (1.8L supercharged) rotors
    adapter plate for calipers (what i will provide)
    machine either the rotor or the hub to fit. (1mm center bore, and 1mm off the hub, or rotor hat)

            I am tuned in. I want to know the size comparison and some pictures. Plus personal feedback for braking feel/performance before I throw down. Machining is no issue for me personally.

                the corrado rotors are also a little thicker i believe.
                here is a picture of the calipers. I have a set on order. the bracket it just an adapter plate to adapt the stock bolt spacing to the rx7 caliper, made out of steel.


                heres a the first picture that came up of a picture of the corrado rotor, cheap ebay D/S thing...

                  I'm more interested in pics of your "adapter" than some off the net stock shots of the parts your planning on using. I see these OE calipers and rotors all day long. I would like to see what design went into these adapters you have engineered. And what grade steel are you using? Do you have tenstile strength of the materials you plan to use? Is this just a precursory pipe dream? or, do you have it all mocked up?

                  Your brother have a machine shop or something?

                    Been done already. I know of a few members at other sites that have this set-up. Now as far as this bracket? I don't know if it's the same one hence why Eli asked.

                        yes, he's an engineer, and he has a CNC machine shop. I will get the grades of steel that will be used as soon as i can get a hold of him. and no, this is not a pipe dream.

                        thats the adapter plate, and as i said before, i will get the grade of steel he's using once i get a hold of him.

                          Looks to be a simple peice, I was just going on the basis that you where using random shots, and that it had not been tested/installed, some other guy right now is blabering about a Jag style brake mod (diff mounted rotors/calipers) on the e30 for "unsprung weight" and I thought he was nutty. Looks like you have tech diagrams, farther along then his pipe dream I guess.

                            I'm in already, seriously. Pending price, I should be able to get one as soon as you have some brackets ready. Keep us updated!!! How much would shipping be roughly to Toronto?
