Oz and Feets made their own from Mercedes rotors and Calipers. I believe 72Swinger used an AndyF kit or made his own utilizing Viper calipers. From my reading, 18" wheels are a tight fit and may require the outside edge of the rotors to be turned down to bring the calipers in a little.
Yep, 360mm x 36mm Mercedes rotor with 8 piston Brembo calipers..no problem with fitment under my 18" wheels, but they are made for extra caliper clearance on race cars, so plenty of room around the caliper.
And as Feets has mentioned numerious times, they are on the heavy side..but hard to beat for the price I suppose.

I called a few weeks ago, he isn't interested in doing them at the moment. The last 5 sets took years to sell.

The mounting system is designed to handle different rotor diameters. You just add a spacer to move the caliper up to go from 13 to 14 to 15 inches.
Thanks for the photo and info, that is helpful to know how easy it would be to change rotor sizes.

I looked into doing the 15" Grand Cherokee rotors and calipers, they are doable on the drum spindles very easily, just wheel fitment was way expensive. Almost 1000 per wheel for the right back spacing. I set up 12" rotors and calipers from a crown vic, cheap to do, easy to get upgraded parts for. Cop cars are abundant and I did my conversion with new rotors for less than $300.00. Tim

I used a wilwood hub on B body drum spindle and added a coleman racing 14" rotor then used US Brake caliper with homemade bracket. Stops my 4000lb Charger pretty good and have never had any fade. I get going pretty good at ThunderHill, but I try to stay off my brakes and on the gas pedal.

Is there any particular reason you want such a heavy rotor up front?
Life will by much happier (easier) if you go with a more reasonably sized 13" or even 14" rotor. Wheels and tires will be less expensive and your performance will likely go up.

cool factor! and the challenge to see if I can make it fit?>  I made the crown vic 12" calipers and rotors fit real easy on the drum spindle, this was more of a mental exercise than anything...Tim

Rotors are not offset enough, no one makes a wheel for less than 1k each to fit a B body. I might be able to get custom rotors and then use an affordable wheel, but Feets gave me crap about wanting to run cheap wheels...so I am stickin with the 12" for now until I get another 20K rounded up to put the car back together. The mental exercise is fun to see if I can make it work though. Tim

I didn't intend to give you crap.
You can make anything work if you have enough money to throw at it.
One reason I used the 2003-2006 S-class rotors was to get the rotor surface back as far as possible. That gave me more caliper to wheel clearance. They get close to the outside of the wheel but the biggest concern is between the back of the spokes and the side of the brake caliper. Multi-pistion calipers are really w-i-d-e.

Wheels with flatter spokes can make it easier...mine is a little tight but works well. I have good clearance on the outside diameter sort of area.

I tried him a few months before that, same story, how many would he need to make it worth his while I would gladly pay upfront...or anyone with the required equipment to replicate it if he has no interest.

I see dr.diff lists a 13" rotor with a 4 piston caliper for my knuckle. Do you know if that is currently produced and where the caliper is sourced from? I would like to get the pedal feel similar to that of my 944 that has 4 piston brembos on all four corners 300mm rotors and braided lines.
I'm in the middle of the install, but I'd say they're generic parts. I know the rotors are Mercedes based. I'm not sure about the calipers.
