I have been searching but have been unable to find anyone who has managed to swap brembos from an srt8 or even r/t disc brakes onto an a body. Looking for any tips or kits. I have found some great deals on both from newer challengers and am trying to find a way to make them work! They would be going on a 1974 scamp.

Thanks in advance!

they make a kit with Calipers that are "Brembo stlye".

Yea, it’s in the link he left exactly worded like that but LOL, he had to double read that!
It is a nice set up by the doctor.

There is (or was) a kit for early Viper brake calipers for A body use.

Ya the Dr.Diff ones look great. I was just hoping to find a way to make the new model srt8 brembos fit since I found such a good deal on them, but it doesn't look like that can be done. I think I will have to stick with viper ones. Thanks!
 
Save them for the LX/LY guys, this is when a good deal turns into a more money to make it work. I have the 13" Dr Diff "Cobra" kit and it's nice. I had similar kit from Baer (speak of which if you want large expensive brakes, there you go) with a 12.5" rotor on my 92' GT and they were a million times better than the factory 11" rotor with single piston brakes were both with rear 9" drums. I did a lot of looking and for my street driven car, dollar for performance the 13" Cobra Dr Diff kit was the winner. Cass is great guy too.

I am installing the 13 Cobra style from the DR. now. Waiting on some parts....On a 69 Dart
 
You’ll have to make your own caliper brackets to run any of the modern Mopar calipers. No one is making kits for them as far as I know. Not that making brackets is super hard, but it would be a custom venture and you’d need to have access to a machine shop.

I run a set of the 13” cobra style brakes from DoctorDiff, they’re pretty impressive on an A-body, even hauling in my 275/35/18’s. You can see them pretty well here. I’m sure the brembo version would be even more impressive.

I looked into it a while ago, general consensus was it's not worth the hassle, will end up costing a lot for some custom parts, and youll more than likely need 20" rims to clear them.
 
I put Jeep rear discs on the back of my Fastback. But I have come to the conclusion that I just dont brake hard enough to need anything but drums... Lol

The Swinger is going to use stock manual drums with small bore master for a better feel.

Well there they are on 18's so don't need 20's. Dr diff has assured me they will fit on my 17's, so no don't need 20's. No custom parts needed either...

For the SRT brakes, or the brembo 'style' brakes from doctor diff? The SRT caliper brackets bolt right on as well? Seems like it would be a more popular swap then, instead of using Cobra brakes for the rear and something else for the front. Let me know how that works out

I think he was talking about the SRT brakes, and I think folks assumed that because the SRT's run 20's you'd need them.

For the 13" kits from Dr. Diff 17" is the minimum, I think there's probably some 17" rims that might not work, but most should. I just run 18's because that's where you see the big benefit of the tie rod end going inside the lip of the rim, so, backspacing options really open up.

I think you're confusing a bunch of posts and kits here.

Dr. Diff sells two 13" brake kits. One that uses 13" rotors and "cobra" style mustang calipers (PBR calipers), and one that uses 13" rotors and Brembo calipers. The rotors and caliper brackets are actually different between those two, only the hubs are the same.

Dr. Diff also sells a rear brake kit that uses mustang calipers, so, if you use the 13" cobra style kit up front you'd actually have mustang calipers front and rear.

As for the wheel sizes, the 13" cobra syle kit works with 17" rims, as I mentioned above. Maybe not ALL 17" rims, but it's been shown to work on a lot of the popular styles for these cars. The 13" Brembo kit I think would be more restrictive for rim size. I don't know for sure if they'll work with 17" rims, I know the calipers are larger than the "cobra" style calipers so at best I would suspect that there would be less 17" rim styles that would work with the Brembo's.

All of Dr. Diff's kits are bolt on. No one that I'm aware of makes any kind of kit for the modern Mopar SRT brakes.

Nope, I'm not confused, he asked about SRT brakes, then others brought Dr Diff into it. There is no bolt on option for SRT Brembos, and you need bigger wheels with specific offset to package them.

As far as Dr Diff, I know they are bolt on, I run SSBC up front and Dr Diffs rear setup with his master, perfect fit, easy bolt on swap, and smaller wheels will clear it.
 
If anyone cares, the SRT brakes can be adapted to the stock spindle.

Scat Pack 4 piston Brembo calipers and rotors

Fell down a rabbit hole and might have climbed out finally. Years ago I built a brake swap kit for myself using ’98 Mustang Cobra rotors, C5 Vette calipers and a simple flat plate to bolt it all up to a stock disk brake spindle. Been on the car for several years now and seems to work well...

And yes, it will almost certainly require 18" wheels and care with style selection to avoid the spokes crashing with the calipers,
