Yes, Ade, the Viper brake kit is from Dr. Diff and is for A-Body big bearing disc spindles. It uses 4-Piston Brembo Calipers from a 2004 Dodge Viper, fixed Calipers, 13" slotted/vented 1.250 thick rotors. He even has a 14" rotor from a SRT Charger but 18" must be used and my Bullits are 17" Ford factory wheels. Scarebird makes a bearing spacer but I wanted the extra strength the Big Bearing knuckle,(spindle), offers.(40% stronger than the small bearing spindles). I & Dave, Wayne, Pat, Drew and you of course,, plan on driving the shit outta this junk pile!!
With a 5-speed OD and 617 HP it should be a very quick ride!
AR engineering discontinued the Viper brake kits for all models so with my Mustang wheels, I wanted an easy solution. Dr. Diff makes them but needs to run a billet 1/2" spacer for those wheels, no biggie, I have spoken to a few MoPar road racers, and as long as the front hubs are chamfered, and the spacer is a well designed alloy, with strong wheel studs, it wont be a problem so that's the route I am taking. It's too late to turn back now as I have 12" rotors on the rear and brake bias is a tricky thing. You cannot dial in bias with a proportioning valve. That valve only controls the "breakover" point of high pressure,,has nothing to do with low speed/pressure operation. The only way to control the bias which is VERY important is to change it mechanically with smaller rotors, calipers, drums ect. Ive spent considerable time and money on this "dream" brake set-up,(fixed calipers on all 4 wheels), manual master, superior brake modulation with little fade
I'm either gonna fook this all up or have a sweet roadrace package.
