Does Cass do those as a seperate item?

Thanks Ade! My Rotors are 13" in diameter and 1.250 Thick. Yes, Cass has kits for the 4 piston Brembo's and 11.75" Cop Car rotors,,of course I think you would have to use pad spacers because the factory 11.75 rotors are a bit thinner than 1.250,,either way it would still be a nice system! Keep in mind the Vipers pad surface area is 5.480 inches The Factory single piston is 5.940 of surface area. This is important for calculating the brake bias between Front to rear. You want at least a 2 to 1 bias. The Dodge Viper is 2.5 to 1 bias but has better weight distribution than B&E bodies which are more front end heavy. But YES,, Cass can supply individual items,,like adaptors,,calipers,,or Masters,,,any component you need or mix and match to suit your brake project. I personally don't like self energizing brakes,(DRUM BRAKES), too hard to modulate and unpredictable and heavy. Kinda like Fat Indiana Women,,,ROFL

I thought you'd already said you were putting 13" rotors on but for some reason the pic of the Bullit wheel makes it look a smaller diameter to me

Yeah,,they look like reg. 11.75" rotors,,LOL,,I cant wait for the HellCats 15.4" 2 piece Rotors with 6-Piston Brembos!! The rotors are bigger than any factory wheel size during the 66-79 Era of course they are using 20" wheels,,need a lot of wheel to clear those Mondo rotors and huge Calipers

All you would need,,are the caliper adaptors Ade,,,to re-use your factory Calipers,,11.75 R-Body Cop Car 1 piece rotors,,,Cass can set you up or you can buy them from mancini racing which are made by Andy Finkbeiner,(AR Engineering). I don't have a pay pal acct. but I know someone who does,,and U can avoid the import scam!

Need to make a small dent in the tunnel for NSS clearance,,no biggie
