How hard can it be?
Did it ever came across your mind - 'what i am gonna do with my front 4 piston calipers' - after installing something bigger there?
I went to 13" 4 piston Brembo setup couple years ago for front of my drift FC, and having some spare 4 piston calipers, i thought about putting them on the back ....
How hard can it be?
I was already running rear 2005 Ford Mustang GT rotors in the back (300mm) and wanted to keep them...and of course, being able to run stock 16" FC wheels in the back for drift trainings....its easier to find free tires for 16 than 17 or 18....
In the end, its not that hard, nor expensive....but its not one of these afternoon basic upgrades either....
First come rear knuckle. I found spare on the shefl, cleaned it up a little and pressed out old bearing, installed longer wheel studs (from front of FC). All back together here :
Installing longer studs is the reason why you have to take it apart and install new bearing. If you want to use wheel spacers with own studs, you can skip this step.
Bolting on adapter is pretty simple, 3 small bolts and one bigger with spacer...
Then the ring for centering of rotor
And now rotor :

Here we are !
And now, special feature for those who must have something MORE
If you have cut the one of the 'eyes' for stock caliper, you can install 2 calipers. In my case it will be one caliper for normal braking and other one for handbrake - independent hydraulic handbrake. Of course, you have run new line for that handbrake...
Thats about it now, i will provide more pics and details once i`ll have it on the car, its too cold for fitting it outside

It uses $20-30 of the shelf brake rotor from Mustang, no modifications
It uses brake calipers from FC (free, from wrecked FC's i parted out)
It uses longer studs from front FC hub (again, free)
And whole package of adapters, bolts and spacers to make it work is less than $150...
And obviously, its rear brake kit, which comes in question after you have done something for the fronts, and thats gonna be more expensive and add some weight too...
Thanks a lot for the products and Def keep us updated on the project

In the front i have brembos with 2x40 and 2x44mm pistons on 330m rotors.
Rear is 4x36mm i think (or maybe 35mm)
Master brake cylinder is 1" from Mazda 929 and if necessary i might go for 1 and 1/16" from Mazda B4000.
I already purchased adjustable brake bias regulator, will let u know how it works

Now, little update.
I had adapter originally designed for Mustang rotor as described in first post and i had made and assembled that way. Everything did fit together, but it required too big spacer for wheels or different offset of wheels than what i had.
Then i came across Toyota RAV4 rotors, which are same bolt pattern, pretty much same size but deeper dish. Center hole in rotor has to be machined, no need for centering ring. Little bit machining of adapters, few spacers for calipers and shaving little meat of the knuckles to clear bolts and final product is here. Only 8 mm wheel spacer is now required and one of my sets of wheels clears it even without spacer...
I can make either version of adapter (for mustang or rav4 rotors).
In the end, it was bit more pain than what i tought it would be in beginning, but its definately doable and every other install will be just easier
