I calculate the force of the brembo pistons and the difference in the torque so i change the rear one with a bigger piston diameter , i do the math and the gt500 rear brake rotor diameter and piston diameter match everything, i was pure luck that i found it , and even better that e-brake works with a minor mod
Lots of hour on Internet getting different oem diameter pistons and rotors , cause i want to keep the e-brake
I was amaze how easy was to fabricate the braket for the rear ones thou

Always great to see a DIY project that works. How does the weight of the new setup compare to OEM? Swept area? Approximate cost of the project? Thanks!

Well i soend about $2000 cause the rotors are about $1000 And brake lines and calipers on the front
And about $300 on the rear
I found a used gt500 rear brakes with calipers and rotors for $140 (really cheap) and the ware use it about 2000miles
I think that the 929 master cilinder was about $150
I dont know the difereence in weight but the rotors ware a bit more , the front ones , and the calipers way more (front ones also)
The rear ware about the same

Good job,
I was browsing ebay thinking about doing something like this. I thought the 17s would max out at 340mm for the rotor though.

My 356mm Wilwood 6 pot kit fits under my 17" Volk TE37 with room.

Yep.. 14 inch brakes will fit under many 17s. Watch where you stick the weights to balance your wheels though.

would be interested in hearing/seeing more about the GT500 rear brakes. What was the piston size? what was needed to mount it? You using stock size rotors or the GT500 rear rotors?

Im using the oem gt500 rear rotors
I only make the center rotor hole bigger, and i made a adaptor braket for the calipers
I think that there ware 42mm the gt500 rear caliper piston diameter but in not 100% sure
The awesome part is that the e-brake was very easy to install and i think that i made a really easy mod only to ware the e-brake cable is attached to the chassis and thats it
I did this long time ago , but cause i was living at Finland i did not have the opportunity to test the car on the track , till one week ago
By the way Im a Chilean
E-brake works better than the oem mazda one now

Cool, those 14" rotors are a tight squeeze! I was looking at a few brake manufactures sites that had a smaller wheel spec'ed for a 17 wheel.

Great work. What modifications were required to mount the front calipers and rotors?

Well lots First you need evo x rotors And evo 5-9 calipers You cant use evo X calipers cause the holder to the hub is too large so it dosent fit Then you have to mill down the calipers a bit , so the evo X rotors fit them (the evo X calipers are exactly the same but milled down) The pad need to fit into the rotor entirely (i left 1mm of clearence so the rotor goes 1mm upper the pad) and the rotor must not scratch the caliper
And then make the adaptor to the rx7 hub Plus you need to open the center hole of the rotor a bit to fit in You need to turn the calipers a bit down to fit them , and the adaptor is very tricky but it can be done I recomend to take the hub out and do it outside the car Not easy not cheap but the resoult is amazing I also change the brake lines for the goodrige ones , but i dont remember the reason , as i remember the hose tread was the same

Here's my question and I know this is an old thread but I just discovered that the brake rotor offset of the 2015 mustang eco boost Performance package is 64mm only 1mm off from the original fd and FC brake rotor and it's a 350mm rotor as well. That would push back the caliper around 3/4in toward the inside compared to the evo x rotor possibly making the caliper be able to bolt up like the stock caliper.... any thoughts? I might experiment with this when I have money to play with.

Could be , i need to check it out , I haved a nice EVO X rotors and EVO 8 calipers (or 5 ,they are the same) so that why i fit them.
As i remember it could hit something if you change the rotor off set.

But i have the car without the tires right now so I can check it out

It should fit but i recomend use a radial monting caliper like the Dodge Viper brakes

I think that you should not have problems with the rotor but will be hard to fit the evo 8 caliper
Cause matching the caliper mounting point with the Mazda hub caliper fitment with the braket was tricky
But as i tould you better use the viper caliper , they use the same front and rears and you can find the rear ones quite cheap at ebay

Some photos so you can see better , the bracket was really tricky to made i guess that with other rotor offset will be quite hard to do it , but if you buy the Viper Calibers should be not problem , i attached a photo of the viper that have the rear brake callipers that are the same of the front , if you but the rear ones used , they are cheap and they are the same that use the EVO front ones but easier to make the bracket.
