The PBR Z06 stuff is junk. Its pretty sad when a supplier can not provide both right and left specific rotors required to keep up with production ?? (Geeze, lets ship the systems with two lefts instead ) Way too many problems right out of the box and maintenance is a PITA.... not to mention that pad replacement cost is a joke as well. The performance feed back I have recieved isnt all of what I thought either..... I was expecting so much more. Its is a great system for a street based chassis, but from what the boys have been telling me, they dont cut it for a serious track day.

Next.... and my first choice, as this is what I am running myself on my 67. APRacing CP5555 fronts and CP5147 rears. They are much better than most available mono blocks for any kind of money (this side of any caliper that cost $3k each). Better performance and cost wise over the Baer 6S/R systems that is for sure. They are lighter, stiffer and some of the available options are priceless. You can utilize a stock C5/6 rear parking brake mechanism and it is a true bolt on. If you can use a C5/6 package, these will fit. I would however recommend an 18" wheel package.... as the rotors are a 14x1.4 front and a 13x1.0 rear.

Front:
Brake Manufacturer: AP Racing
Caliper/Piston Number: CP5555, differential bore six-piston
Rotor Manufacturer: AP Racing
Rotor Type: Slotted 2 pc, McLaren floaters
Rotor Dimensions: 355mm x 35.5mm (14 x 1.4")
Wheel/Tire Size: 18x9.5 265/40/18
Tire make/model: BFGoodrich g-Force T/A KD
Brake Line: Stainless 3/16" hardline, Goodridge SS Flex lines
Brake Fluid: Motul RBF 600
Pad type/compound: Ferodo 2500
Master size: 7/8"
Weight: 33.5 lbs
Combined left and right: 67 lbs



Rear:
Brake Manufacturer: AP Racing
Caliper/Piston Number: CP5147, four-piston
Rotor Manufacturer: AP Racing
Rotor Type: Slotted 2 pc, **NEW** Iron hat, factory e-brake compatible
Rotor Dimensions: 330mm x 25.5mm (13 x 1")
Wheel/Tire Size: 18x9.5 275/40/18
Tire make/model: BFGoodrich g-Force T/A KD
Brake Line: Stainless 3/16" hard line, Goodridge SS Flex lines
Brake Fluid: Motul RBF 600
Pad type/compound: Pagid RS421
Master size: 1"
Weight: 27.5 lbs
Combined left and right: 55 lbs



This is the Holy Grail of brake systems.

I have installed and used various systems from every manufacturer..... (Alcon, AP Racing, Brembo, CNC, PBR, Perf Fric, JFZ, Stoptech and Wilwood) which also goes for pad/compounds (Axxis, Carbotech, Ferodo, Hawk, Pagid, Perf Fric, Porterfield, Poly Matrix, Raybestos and Mintex). The modulation, fade resistance, predictability and shear stopping power of these independant systems is nothing short of phenomenal.

Think.... 60-0 in under 90 feet.

C5/6 think.... 60-0 in around 105-112 feet.

Really interesting post. Obviously you have a great deal of knowledge regarding this subject.

Based on the Qualities I had outlined, would both of these systems fit the desired parameters? I realize there is a great deal of difference between the two.

Can you give me a rough estimate of the cost involved with the AP Racing Bakes you have vs. the C6 Brakes you mentioned? (Both upfront cost and maintenance)

I noticed the part number you mentioned for the rear brakes has probably changed from the newer part numbers. Do you know the newer number?

Where did you purchase your brakes?

Any difficulty finding pads for these?

Thanks again for the great post.
