Gen2 STA Six Piston Brake Upgrade

[Supercharged SVT]

Has anyone successfully pulled this off? I just picked up a Donor Spindle with hub from the salvage yard and we will start this project this month at the engineering shop to fabricate brackets and manage the offset - SuperCharged SVT is slated to receive some TLC - 15" Rotors up front with Ford GT500 6 Piston Brembo's plus 14" Rotors in the rear with Ford Brembo 4 Pistons and stand alone eBrake - This project is way overdue - Got donor parts from a conversion shop down south.



There was a guy on here that did a 4 piston upgrade, I think i offered him crazy money for the brackets and I never heard back - I will post as we go and let you know IF its even possible.

i looked into it, even considered buying the front knuckle/hub assembly like you did, good idea.



the adrenalin wheels have pretty low clearance between the hub face and the spokes, you will probably have to use a 2 piece rotor with a high hat offset to get enough caliper clearance.



the rears will be much harder because the caliper mounts inside the cast rear knuckle. you can't just make a bracket and put on a larger rotor. you will need to do a lot more fab work and cutting in the rear. I'm sure just an upgraded front set would make a huge difference alone.



if you end up making some adapter brackets for the front to use calipers like wilwoods, etc, i would buy a set from you, im sure you'd sell quite a few sets, good luck!

we just looked at everything at the shop and it will be an offset of .20 and then the bracket needs to come up 1.2 - this is going to be easier than one thought - the GT500 15" rotor is a Perfect for the STA hub - same bolt pattern as expected and snugs perfect



the spacing on the spindle is off .30 but no biggie since we have to come up - After the mock up we will try the wheel but from the looks of it, the 15"s push the caliper up on the radius and the wheels themselves move out - rough measure shows a perfect fit - hopefully in a week or two

Please add pics... I've very interested in this

rotor fits perfect - just so you know the size - I wear a size 9 shoe -



the bracket looks easy it will be a double offset item to keep everything centered -

***Mock Up on 2010 STA spindle with a 5/16th spacer - it fits perfect inside the rotor - Bracket is next and then the wheel mock up followed by the Brake Lines

What donor cars would we be looking for if we were to take on this project?

These came from Richard Petty Racing - they were pulled off a 2016 5.0 Mustang with the Track Package with 30 miles - I also picked up the 13.8" rears that seem to match up with the Motorsport Conversion Kit and fit - They are single pistons but much bigger and the factory rotors look so small. When the fronts get done and we get them in, I will see what is needed on the rears - I have a Bias Valve just in case they are way out of balance - no sense looking my fillings when I squeeze on them
