Following the installation of 14" rotors with 4 piston Brembo brakes onto the front, i'm wondering if i installed 14" rotors on the rears as well, would the stock calipers work?
if yes, how would such an installation go? do i need any special hardware to adjust the caliper mounts, etc?

 

Both the Shelby & the FR500C use the stockers. If they work for them, they'd work for me!!

 

I didnt think the Shelby GT500 used 14inch rotors, I believe they have the same brakes as we do, as does the FR500C. What 14 inch rear rotor are you looking at?

Also, did you put the GT500 brakes onto your mustang up front, or a Brembo Gran Turismo brake package?

 

The stock rear calipers are designed to fit the stock rear rotors which are far from being 14" diameter. You might be able to build an bracket to offset the caliper so it accommodates the larger rotor diameter. Your only hurdle then would be if the 14" rotor is thicker than your stock (probably is) ... in which case you will have wasted your time.

My recommendation, get the right parts ... you did it on the front.

 

Baer EradiSpeed +2 for the rear come with 2 pcs. 14" rotors and a new anchor to mount the STOCK caliper.

You will need a brake hose approx. 1 inch longer than stock. The Baer kit does not come with hoses.

They can be had for about $600 or less
