I have 14" brakes off the front end of the gen 3 & 4 vipers. 4-piston brembos and 14" rotors. Brakes feel great, stops NOW and inspires confidence in your ability to stop short when needed. Pedal modulation to avoid lock-up is easy. Snd despite efforts to heat them up with repeated hard stops, I've not experienced brake fade yet.
Wheel size, I doubt you could fit 17" wheels over these, never tried myself though. 18" is probably the safe minimum diameter.
I wouldn't go bigger than 14" rotors unless I bought super expensive aluminum hubs with bolt on rotor surface area to reduce weight. These stock viper rotors weigh around 30lbs each.

Nice setup. I'd like to know more about your mounting brackets, and which spindle you're using. Along with the hub set-up

So I notice here for almost the first time in a decade, a brake size discussion "of mine are bigger then yours" on brakes that includes more then a mere suggestion on the package weight. We have actually made progress.  To bad its a little more complicated to include MOI in casual rotor discussions since diameter is such a factor.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

IMO, weight matters, but in a different way than you're saying.
Ideally, you want the lightest rotors that will handle the heat. For less-than-competitive racing, I like my 28 pound rotors- they're a huge heat sink and stave off brake fade.
A point of reference - Matt Robertson road races a dodge magnum, and switched from lightweight 2 piece rotors back to factory rotors. Why? Because the two piece rotors were very expensive and wouldn't hardly last a weekend. The factory SRT8 rotors last multiple weekends, cost much less, and didn't get as hot doing so.
I agree that increasing unsprung rotating mass isn't good, but it doesn't outweigh the benefits of the increased heat sink (i.e. weight) for most.

I suspect that brake technology has progressed in pretty big strides lately, in the area of pads/fluids. I have been around racing applications since discs (solid) were introduced. And surprisingly Nascar had to wait for the technology to progress enough before they became a user. That said, and I have said before, any un ducted brake system that can lock a tire in use, and doesn't fade, in competition should be considered over capacity in whatever way you choose to measure. Racers have for decades added ducting/blowers to be able to reduce the size of the heat sink, and all the benefits that reduced heat sink provides. I am doubtful many here are experiencing brake fade with a properly set-up brake system ( balanced correctly, correct pads for application, fresh bleed fluid). Anybody suffering severe brake fade has a problem with their brake system, or it s undersized for the application, or their driving technique might be in need of improvement. The only way to actually determine that, is to push the system to point of approaching brake fade. That should not be hard to do, if the system is balanced properly, concerning suspension, F/R, HP, etc. If that fade is difficult to achieve, ducting will provide more then enough safety margin for one's peace of mind, if it the can't, something is not in balance and you have brake system overkill, to a proven performance detriment. I have heard others say that brake ducting is difficult, well only if you haven't tried, and F1 aero is not a big concern. Anything is a lot better then nothing. I also get a kick out of the bigger brakes givening better modulation crowd, well if you are braking at 100% thresholds at over 100mph with the typical cars here, you are first 1 in 1000? and can't be gaining much insight on this forum. If you are running under 100mph and or autocross, your oversize brakes are costing you time. FWIW at the recent optima Daytona,less then 1/3 of the cars had brake ducting, which for a competition event seemed rather strange, it was hot, it was long, and Daytona was/is likely one of the faster courses in the series. No way to find out reliability what factor brake fade played, on most of the big brake cars. remember it is 3+ miles long, serious banking, and possible to hit 160mph. I think the last paragraph is fairly accurate, and I'm sure there will some disagreement on how to interpret my observation.

Curious if anyone is running 14" brake rotors and how they worked out for wheel sizing and feel.
Whos kit and price would be nice too..
I have been looking at the Bear 14" with the 6P calipers, but they are $2,400+ each end.
I'm running this kit on the front of my car and I like it. As far as overall weight is concerned, it was a wash between my 10.875 rotor, slider caliper setup and the baer kit. Also 13 or 14" rotors are the same price. I like the pedal feel on mine, but I might try a different master cylinder bore to lessen the overall pedal travel a little bit. At willow springs, I didn't have any issues with fade. I think I was ~110-115 at the end of the straightaway into turn one so my car isn't as fast as others on here. I'm running the 11" stock drums in the rear. I also won't claim to be a great driver as this was my first track experience - just my 2 cents

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.

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 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.

My calipers are 8 piston Brembos, so might be a little larger then those as well? (On 360mm rotors) I still have decent clearance to the spokes of my wheels...but every combo will be slightly different I would say, depending on wheels with spoke shape, mounting pad height, and rotor height people use.  (Mine are 2 piece, so no bolts along the inside edge eight depending on how close people's calipers may come to that area?)

It would have to think it would be way less than half the weight of mine easily if not more.. (and an inch larger in diameter) I might toss it on a scale tomorrow for the heck of it. Still waiting for the other 3 rotors to turn up for him too, be any day now I would imagine.

Speaking of large brakes...check this out...a buddy in Oz ordered a set of brakes for a ZR1 that he is going to retrofit onto a Torana (like mine). Carbon rotor, HUGE (nearly 15.5") and weighs next to nothing !  
Having the billet hats and the carbon disc is probably a 40 lb weight reduction off one end of a car if you replaced steel with those.
13.2 pounds for one!

Speaking of large brakes...check this out...a buddy in Oz ordered a set of brakes for a ZR1 that he is going to retrofit onto a Torana (like mine). Carbon rotor, HUGE (nearly 15.5") and weighs next to nothing !
Having the billet hats and the carbon disc is probably a 40 lb weight reduction off one end of a car if you replaced steel with those.
13.2 pounds for one!
Vs probably close to 50 lbs for a similar 15.5" steel rotor. That's a lot of rotational energy you're saving.

I would have guessed 2500 per rotor, but at 1500 per, that is a lot cheaper than other offerings at SEMA that were in the 9-11k price range.
of course the term "cheaper" doesn't really apply here.
cool stuff!

Funny to think of close to $6k for 4 rotors as "cheaper" but know what you mean.

Those rotors aren't any good, they're drilled. I heard on here that drilled rotors are no good because they crack between holes.

If you look in the archives you'll see a couple of magazine articles that I wrote on Tim's Valiant. We put a 13 inch Baer 6P kit on his Valiant and it works fine. Tim's car is road raced and has 150+ mph capability so it is very fast for a vintage Mopar. We could've gone 14 inch or 15 inch on the rotor size but there wasn't any reason to do so. The 13 inch rotors do the job from 150 so why go bigger. A 14 inch rotor does give you a little more leverage and a little more surface area and perhaps some additional head sink. I doubt that very many guys on here have a car that is fast enough to require a 14 inch rotor but nothing wrong with putting them on a car if you have the cash and don't mind spending it. I'm probably the only one on this board who has not only had both the 13 and 14" systems, but has had them on the track as well. My Dart is probably 600lbs heavier than Tim's Valiant which plays a huge roll in brake performance. Another thing to consider is feel and balance. This is almost more important than the brakes themselves. Most on the board don't understand this factor. Even though the 13" system was adequate, the 14" is far superior in braking and confidence. I had the complete system working for years and changed to the 14s by themselves. I also run an expensive set of Carbotech pads. Bottom line, if you can afford it, brakes are worth it!

There are three reasons for reducing weight of brake assemblies:
1. Overall vehicle weight.
2. Rotational acceleration energy use.
3. Reduced unsprung weight.
The first two make the vehicle easier to accelerate, And slow down.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Peter,
What brakes and spindles (make,year, drum/disk) are you running now? I know you've got your car sorted out well!
Thanks, Wes 73 UP A Body disc spindles. Gen 3 Viper Caliper, Carbotech XP20 pad, OE Srt slotted rotor.

Cass made them many years ago. Aside from some of the Porsches and Stoptech equipped XV cars they are one of the best brake systems I've ever experienced. Thanks-Wes

I run the same fronts as Peter. I have a few sets of the correct calipers if you wanted to get the correct bracket from Cass and copy the kit.

I think any of the disc brake setups will be lighter than the 11x3" drums that are on my car now.
Actually no.... I thought that until I had both set ups in front of me on the scales, the 11.75 c-body set up is heavier than 3" drums by a couple of pounds
