Description
Stock vs. JHM
-Rotor OD: Stock C5 A6 or Allroad 2.7t = 255mm(10.03"), JHM = 325mm(12.8") - Almost 3 full inches LARGER
-Rotor Cooling Air-gap: Stock = NONE, solid rotor, JHM = 13mm(.511") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = NONE, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor Thickness: Stock = 10mm(.393"), JHM = 22mm(.866") - LARGER for better cooling by being able to add fins.
-Bolt pattern: - SAME (fits like an OEM rotor would)
INSTALL NOTES: Due to the relocation of the rear caliper making it more outboard you are required to unsnap and release the plastic sleeve for the parking brake cable in the lower rear control arm. This is necessary to allow the cable to be pulled rearward some so it can reach the caliper without kinking or excessive stretching. (NOTE: This sleeve is usually brittle and prone to breaking and sometimes hard to release, so do not be worried if it breaks when performing this mod. As long as you can get it so the cable can be pulled rearward some you did the job correctly)
INCLUDES:
2 - JHM 2-piece Lightweight 325mm (12.8") Rear Rotors.
2 - Caliper adapter brackets CNC machined from 1/2" steel with a high quality zinc coating. (These are supplied to us by 034 Motorsport since we didn't see the need to make these as well and thus allowed us to get our BBK to market quicker with our larger B6-B7 S4 rear lightweight rotors)
4 - Caliper adapter bracket mount bolts (also supplied by 034 to us)
NOTE: You can reuse your stock rear lines or upgrade to some stainless lines available separately
-Works with stock replacement B5 S4 rear brake pads. Such as OEM, Hawk, PBR, Mintex, Etc. We sell pads as well, if you do not see the ones you want contact us for details.
