Default How hard can it be? DIY brake upgrades
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


Fullsize pics are here :
