What are the option for pads. The car is used on the street a lot and some track days.

Does anyone else make rotors that fit? 13.1 x 32 mm.

It's a little trickier to get pads for the Alcon B-type 4441 four piston caliper than for most other aftermarket calipers because of their relative rarity. I get mine from EBC through Summit, although they have to be special ordered and it took a couple months to get. I use the Redstuff pads for street and light track duty, but Green and Yellow are available also. Yellow is the track pad. Carbotech makes pads for the B-type as well; Bobcat 1521 is street/track and AX6 (Panther Plus replacement) is the start of the track pads. The higher numbers are considered track only due to dust/noise concerns. If you go for standard Textar pads from Baer they'll cost you about $400 dollars (I live down the road from Baer, so I picked mine up and it still cost me $375 for one set) and they're horrible so I would avoid them. Hawk offers HPS, HP plus, Blue 9012, DTC-60 and DTC-70 compounds to fit Alcons. I used to use Blue 9012 pads for heavy track use; they work great. They're ok for street use. The DTC pads are extreme race-only pads that suck cold. HPS and HP plus are street pads. Polymatrix makes Alcon pads in their "A", "C", and "H" compounds, but they're meant for racing use only. "A" is the high torque/response pad for severe endurance racing, "C" and "H" are reduced friction for brake biasing. Pagid has eight compounds available using the 1595 backing plate; RS4-2-1 seems to be the only street-worthy pad. I'm sure Ferodo makes pads to fit Alcons but I can't find any application chart. Shoot them an email to make sure.

Here's some part numbers:

EBC: DP2016 Greenstuff, DP3016C Redstuff Ceramic, DP4016 Yellowstuff
CarboTech: 1521 Bobcat, 1106 AX6, 1108 AX8, 1110 AX10, 1112 AX12
Hawk: HB105F.620 HPS, HB105N.620 HP+, HB105E.620 Blue 9012, HB105G.620 DTC-60, HB105U.620 DTC-70
Polymatrix: 15A-5872K "A", 15C-4416K "C", 15H-8113K "H"
Pagid: 1595 backing plate, RS4-2-1 street; RS4-2, RS4-4, RS5, RS14, RS15, RS19, RS29 racing only compounds

For rotors, if you have the Pro kit it uses one-piece 13"x1.125" Corvette ZR-1 rotors available everywhere. Pro+ kits with 13.5"x1.25" two-piece rotors need replacement discs from Alcon; I'm not aware if any other aftermarket rotor disc will fit the center hat. Remember, if you have 1.25" rotors you have to make sure you get 16mm (.620") thick pads; if you get 18mm (.708") or thicker pads they won't fit.

WOW....Thanks for all the great info.

The pads I have now are Ferodo and really like them for light dust. Sounds like the EBC's is what I am going to get.

My rotors are the one piece type and was hopping that it was a common part with the HD brakes on C4's

Will post pic's once completed with the completed set up.

Yup, they're the same. Autozone has blanks for $50 each, and they're fine for street driving.
