Machined the Dakota rotors as hubs to fit the Crown Vic stockers. No mods to the Crown Vic rotors.
The other part of this may be "can the 13" Mustang rotors also be used"? Answer is Yes, but. Yes, they will also work, but they have "less hat" than the Crown Vic rotors. That moves the caliper farther away from the steering knuckle and requires a thicker wheel spacer. So yeah, it can also work.

Are longer wheel studs needed?

Geez that Dakota hub wheel face is Uber thick, does that take standard mopar/fmj wheel bearings ?? I plan on doing some thing similar with my volare, but I am using Mustang cobra rotors front and rear, and brembo 4 piston calipers front and 2 piston rear off a 2005 Mercedes clk500, I can't wait to see how this turns out, and I plan on upgrading to 18" wheels, but I am trying to stuff them inside 17" wheels also using large bolt pattern hubs from a mid 70s duster that had drums up front

I'll see if I can pull the rotors off this weekend and let you know if the Dakota "hub" will fit the F body spindle. Also, I think I mentioned that I see no problem with using this combo with 13" Cobra rotors other than it positions the caliper further away from the steering knuckle and MAY (or may not) require spacers. Late edit: Dak "hub" won't work on the FMJ. Dak spindle is bigger.

Now you got me thinking get if the Dakota spindle has the same dimensions as the fmj, but I believe the fmj is taller, I just rockauto searched and the ball joints are different, but with out physically measuring I wouldn't know the difference, looks like when I hit the junk yard today or tomorrow I'll see if I can find a fmjob to use as a test stand, and I know they have older Dakota state so this should be intresting

Dakota spindle is thicker. Dakota is front steer and FMJ is rear steer so the Dak hangs the caliper in the back while the FMJ hangs it in the front. That said, if you work with the FMJ stuff to try this you can really leave the Dakota parts out of the picture. If you hit the junkyard, grab a couple of nasty, rusty old FMJ brake rotors and a nasty, old 1998-2002 Crown Vic rotor AND hub. Oh, and while you're there, locate a couple of 95-00 LS400 calipers. See if you can get the shootin' match for under $60. After that, you're on your own! Greg

A quick update and maybe you'll see something you didn't know. I picked up a 12" X 24" X 1\2" thick steel plate ($36) to fabricate the caliper mounting brackets. Made a cardboard template, then drew the outline on the steel plate. Dropped off the plate, template and spindles at the machinist. He'll get back to me fairly soon. In the meantime, my curiosity got the best of me about how this setup would work in other sized wheels. I know it works in 17" and 18" wheels, but what about 15" wheels? It so happens I have a set of 15" Mopar Cop Steelies sitting in the rafters so I got one down to check for a fit. Guess what? It sorta fits. Sorta? Well, when the Dakota hub, Crown Vic rotor and Lexus caliper are placed in the Mopar 15" wheel, the tapered portion of the rim fouls the caliper. BUT, if you run a 1\2" or 3\4" spacer, you've got all the clearance you'd need. So, that's the answer to the question nobody asked.

So if somebody asks "Can you mount a Lexus 4 piston caliper onto a Mopar passenger car spindle?" The answer looks to me to be "Yes". Of course, the best part is it didn't cost you anything and maybe you learned something. Please don't ask me about master cylinder's and bore sizes. I haven't gotten that far yet. I do know the Lexus master cylinder has a 1" bore size.

I went with crown vic brakes front and explorer rear, the explorer rears were the same size piston as the crown vic rears. installing the fronts on standard drum brake spindles and hubs with the rotors that fit perfect. Took a while to find compatible studs, but should be a simple upgrade because ford already did the engineering for me. Tim

I took the factory FMJ style brake rotors and cut them into hubs for my AMG brake conversion. Your thread made me think about all the fun I had putting my combo together.

I build my own cailper bracket by using Autocad. I 3D printed the bracket first before milling them.
I used the 2003 Mercedes rotor and a machine shop milled the mopar bolt pattern in them. For the caliper I used the Brembo caliper, 6 pistons, type Z18 used on a Porsche Cayenne.
That is EXCELLENT! However, I had to use a Sharpie, a pair of scissors and a piece of cardboard before I gave the plate to the machinist. Almost done with final mounting.

That is what I call CAD. Cardboard Aided Design. I do it too.

I'd have to do some pretty deep digging to find any pics of building the parts. Pics of the finished project are easy to find.

WOW!!!! Now I kinda wish I'd used the larger Mustang Cobra rotors or the SRT8 rotors. But, the Crown Vic stuff keeps me in my budget. What did your whole brake project run you? AMG calipers don't fall off of trees. I just spent another $200 bucks to my machinist to fab my brackets so I'm still under $500 total for the swap.
Man... that sure is pretty.... I had about $2400 in all four calipers, pads, and rotors. That was in 2005 when there were no big brake kits for our cars. These are the front 8 piston calipers and 14.25" rotors as well as the rear 4 piston calipers and 13" rotors for a 2005 S55 AMG. I work at a Mercedes store and got them at my employee discount. As for the work, I have a machine shop at home. My first set of brackets were made by carving up old 2x4 lumber then copying it in steel.
