I wanna see this with rear mounted high performance brake calipers. I've never seen an A-body Hotchkis Upper Control arm with anything but a stock caliper and rotor 11.75" or 10.75"
BTW you cant run rear mounted 11.75" stock pin caliper setup with the Hotchkis Upper Control Arm.

I'd be test fitting the caliper on there stat because I'm kind of doubting it's not going to hit. My 11.75 Sliders hit basically 1/4" above full droop and I had to swap them to the front.
I know the Dr. Diff Cobra calipers will fit since there is a front mount option. Not sure about these.

Watch your clocking on the strut heim as well. You should tighten everything down at or about ride height and make sure that all the heims are in a neutral position.
I didn't get around to clocking the strut heim and nothing is torqued down. Thanks for the heads up!

Good point. I didn't think about that till you mentioned it. I know someone put this brake kit with the Cobra Calipers on a Duster, but I don't recall which UCA's he used. Maybe FirmFeel.

I'll try different configurations. If not, I'll try front mounting them and hopefully they shouldn't interfere with the sway bars.
I doubt it would hit the hotchkis sway bar...if anything it would hit the strut rod. Doctor Diff says they must be rear mounted on the website. Maybe he knows the exact reason for that?
If that's the case, I'll have to either sell this brake kit and either buy a Viper/Wilwood kit or I'll have to sell these UCA's and install a Firm Feel or large ball joint set with MOOG offset bushings. I still have my large ball joint drum spindles. My friend and I are going to test fit the calipers tonight before we proceed with anything else.
Edit: Still waiting for my friend to arrive, but I bolted up the caliper. It definitely looks like the UCA is going to hit the caliper. Just by looking at it for a couple seconds, it doesn't seem like front mounting the calipers will interfere with the strut rods. I don't think it would be much of an issue so long as I keep my bleeders pointing up.

Yes you can switch spindles and your calipers will be mounted in the rear.
I was really worried 3 years ago when my stock rear mount calipers hit those Hotchkis UCA's. Hotchkis saw the interference first hand. I thought they were going to add that info to assembly instructions.
I just hoped an aftermarket caliper would clear. But I've been looking at Wilwood and DrDiff setups at shows for years and just knew I was hoping a square peg would fit a round hole.
My plan is to run front air ducts with rear mount aftermarket calipers. Running air ducts to the front is much cleaner than the rear. And I don't even think there is room with the shock to get a 3" duct to the rear.
This S*CKS 
My friend jokingly asked me, "If you want, we can machine your caliper." I took a look at it and said, "What are you going to do, machine off the entire bleeder?" It was pretty bad. At full droop, the caliper didn't hit the UCA, but they overlapped by an inch or so.
What would be the issue with running a brake duct to the front of the rotor beneath the caliper?

Is there that much room there to do that? Could you take a pic from the inside when you get the rotor on.
Also, a 3" duct will sit very low with the caliper up front. Most likely below the LCA.
What is also bad is if a customer was running a Hotchkis UCA with stock or non Hotchkis aftermarket front sway bar that mounts to the stock sway bar mount on the LCA. Those customers (potential customers) typically run the calipers to the rear. There are 4 combinations of that rear caliper setup:
rear pin calipers 10.75" rotor
rear pin calipers 11.75" rotor (I've tested, does not work)
rear slider caliper 10.75" rotor
rear slider caliper 11.75" rotor
I haven't tested the 3 other combinations. IMHO, it's a higher than 50/50 chance are they will not work.

I'll take some pictures when I put it together, possibly sometime next week. But I see what you mean, the brake ducts will hang a little low. How low is the question.

I agree, it should be put in there instructions. My friend and I discussed that as he could see it wouldn't be able to work with his Demon. I believe Tomwheels has 11.75" disc brakes on his Valiant, but I don't recall if they were front or rear mount, pin or slider. He's got the full TVS.

That is ALOT of money for arms that don't let you run calipers however you want.
Mopar to the bone!!!

We built Tom's car with front mount calipers.

They run the wide bend so the tube is inline with the spherical rod end. That puts the ball in the spherical inline which is best to reduce wear and loading. Magnumforce does the same thing with one of it's upper control arms.  I've seen this setup below on other production aftermarket, circle track and other type race cars. It's just more costly to manufacturer which drives the selling price to customer up. And Hotchkis is pushing the price point already.
