What kind of braking force improvement can you expect with this as compared to a 2.75" single piston caliper with a 12" Cordoba rotor ? I don't know but I suppose there is a reason the Mopar engineers didn't use the Cordoba rotors on the Viper. WEll, yeah.... I understand that weight is a big part of it, right? I was not criticizing at all, I was wondering about the math of it. I did not see the size of the rotor or the piston configuration of the caliper so... Thanks though. I'm just copying what the factory engineers did. They put these parts on the Viper so I'm putting them on my car. The Cordoba setup is 30 years old and was designed for a car with a top speed of 120 mph.

I run Cass's Stage 4 brake kit currently.
In terms of total piston area, I believe the current calipers he offers in this kit would be similar to the 4-piston GEN II Viper calipers. The calipers Cass provides use an 03+ GEN III Viper brake pad already.
So, what am I missing here other than the (possibly) lighter, two-piece rotors? Just the ability to use the authentic Viper calipers?

The Viper caliper would be a lot nicer though since its made by Brembo. I have Cass's Stage 4 kit also but I have Carbotech pad 592 which is for a 2001-2002 Gen2 Viper and it works great! Hauls 3400 lbs. down from 140 mph with no problems.

Got a quote from Cass. Whoa these rotors are pricey haha! Andy can you please post up the 1 piece vs. 2 piece rotor weight? Trying to justify cost to weight, need vs. want ratio haha! Thanks!

Hey andy the viper caliper bracket looks the same as the one I bought from you years ago that fit the 13" Mercedes rotors - are these the same or is the new caliper bracket different? Whats the weight savings on going from the heavy 1 piece rotor to the new 2 piece? The offset on the hubs is different between the kits. The kit I used to make pushed the wheel surface out so that Mustang rims would bolt on. Cass has his wheel surface in the stock location. So no, the caliper brackets will not interchange.

Cass will have to answer that. From what I understand there might be a supply issue getting the knockoff caliper. The OEM design should be around for a long time since Vipers will be around for a long time. Downside is cost of course.

Two piece rotors are 4 lbs lighter per side. So 8 lbs of unsprung weight off the front end. Thanks so much Andy! Unfortunately the 2 piece rotors and shipping to me would cost nearly $120 bucks per pound so the price is hard to justify as Cass's Stage 4 kit works great just heavy. I also have a spare set of his 1 piece Mercedes rotors already. I would rather spend that money on more track days. If someone were to start from scratch I would definitely recommend your kit with Cass's 2 peice slotted only rotors!

Viper calipers are a radial mount? What is the ctr to to ctr stud spacing and/or is it common to other caliper options?
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Viper calipers are a radial mount? What is the ctr to to ctr stud spacing and/or is it common to other caliper options? All of the high end calipers are radial mount. Take a look at any Porsche or Ferrari and you'll see radial mount Brembo calipers. The Corvette was the only super fast car that was bucking the trend but I think GM engineers finally saw the light on the track cars. Center to center on the Viper caliper is 130 mm. That is a fairly common measurement but I wouldn't bet that all Brembo calipers use the same dimension.

The mounting adapter bracket that bolts normally to the spindle and connects/bolts to the caliper one of two ways with two bolts/studs, perpendicular, or parallel to the rotor, ie radially, the later allows additionally, small adjustment of tuning the caliper operating radius. A pic is worth a thousand words, the pic in this thread unfortunately is not overly clear, hence my original question. As mentioned, radial mount is the current preferred method.

Andy -- T/Anks for posting the new option for us.
I'm at a point now in updating to the 'Cordoba 11.75 diameter, using my pin-type original calipers... just have to order the 11.75 rotors and bearings (spindle updated to later a-body). Just still wondering what could be better than that... while still keeping the allowable usage of the factory 15x7 rally rims. I tried that rim onto a Viper caliper setup (thanks to a local cool Mopar guy having the setup on his awesome '70 Charger!) with the 11.75 rotor and the inside of the rim hit the Viper caliper (would possibly clear by using a ~1/4" spacer for the rim-to-hub... not something I want to do). Also, I have SuperLight brand 15X8 mini-light rims for street/hwy-cruising and they have barely any inside diameter clearance against the top of the Viper caliper (especially the inside tape weights -- they touch the caliper during wheel rotation. I really wanted to go with the Viper setup and 11.75 rotors (and I have a set of the correct spindles aside), but the interference issues cautioned me away. 16" rims are not a problem which I've checked and confirmed. I'll probably just use the cast iron pin-type calipers and be done with it.
