Are RX7 hubs the same/would this fit?

Alright, I figured this was a good place to dump my retarded question.

So, what advantage save increased mass/cooling area do the Corrado rotors in the M-Tuned brake kit offer compared to just the stock 1.8 set? I understand pad size stays the same, so the overall friction area remains equal yes?

The fact that the rotor diameter is larger means more braking torque, all else being equal. Geometrically (not thermally speaking), everything else is the same.

If you want to know more, there is a good book called "The Brake Handbook" or something like that. When I designed the braking system on our FSAE car it was my bible.

So someone gave me a set of front RX7 brake calipers for free. They look to me to be a little bigger than dynalites, but not by much. They weigh less than stock calipers as far as I can tell and have 4 pistons. I'm seriously considering a retrofit. It really doesn't look like it'd be impossible. Rx7 Calipers plus corrado rotors would do just fine for me I think at the track.

Contact TravisR or Savington from Track side engineering, there might be a market for brackets for these calipers, they can be had for very cheap.

I think there was a member that fitted a set, I want to say it was reddroptop...the guy with a mirrored image of his classic red in his sigline.

It would have been almost a year ago.

Mazda RX7 Turbo II/GTU Aluminum 4pot calipers w/pads:eBay Motors (item 160359401320 end time Oct-29-09 21:01:01 PDT)

Two for the price of one. Found some cheaper ones but they were dirtier, and I figured they wouldn't be good enough for you. I'm just saying they can be had for cheap, at least cheaper than brand new ones (free if you're wayne curr) and a mounting bracket should be similar.

You can't drink all day if you don't start in the morning.

I know at Road Atlanta, my sport brakes with HP+ pads and ATE super blue I was able to get fade pretty easilty for 10a when trying to slow from 130mph 50mph and at Talladega Grand Prix(much smaller track) I barely got fade. I finally got some stainless lines, new HP+ pads and fresh fluid in there and couldn't fade the brakes at TGP the last time I went out there. Mind you this was all on Hankook Z211 C50 compound slicks. If I had been on a more streetable tire like Azenis, Z1 SS, RS-2..I probably wouldn't have had any problems at all.

But for ****'s sake, I have since installed a Brembo GT kit consisting of 12.5" rotors and 4 piston calipers
When you wrote "I finally got some stainless lines, new HP+ pads and fresh fluid in there and couldn't fade the brakes at TGP the last time I went out", did you mean to say something besides HP+? It looks like you said the only difference was your lines between the two setups. I didn't think lines made any difference besides "pedal feel".

Did you mean to say Hawk Blue instead of HP+?

Here is a good picture of the RX7 Calipers on an E30. Pretty common upgrade in their camp. I still haven't even eyeballed the calipers on the miata spindle so I'm not sure how they'll mount or if it will be easier or more difficult than this E30 application.

Here is the back of the caliper installed

It cant possibly be that easy in a Miata.

Edit:

And another pic of them on a volvo.
