Racing Brake Rotors - 2 pc front (replacement)

Racing Brake

$640.00

Size: 340x31mm (13.5" x 1.4") Z51 and Base Model
Rotor Wt (lbs.): 16.7 complete vs. 20lbs OEM

 

This rotor ring is a replacement for RB two-piece.

Comes with the necessary hardware for each disc.

Rotor Material: Racing Formula Alloyed Gray Iron & Heat treatedåÊ
Machining: Open Slot
Surface: EDP Coating w/cross cut grinding on friction surface

Material:

  1. Alloyed iron formula adds strength and heat resistance. Heat treating further improves rotor performance for a more uniform and stabilized microstructure.

Design:

  1. The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. (Illustration #1)

This rotor package fits the following vehicles:
åÊMODEL åÊYEAR
åÊCadillac CTS-V åÊ2009+
åÊCamaro ZL1 åÊ2012+
These rotor hats have five lug holes to fit the V2 CTS-V hubs. If you are looking to upgrade your setup from the V1 CTS-V (which has 6 lug holes), see p/nåÊ2189.

Rotor Material:åÊRacing Formula Alloyed Gray Iron & Heat treated
Machining:åÊOpen Slot
Surface:åÊEDP Coating w/cross cut grinding on friction surface

NOTE: Retaining and jack screw holes might have been eliminated to prevent the screws from stripping and breaking, causing tremendous effort to remove and replace the rotors. Our two-piece rotor hats are made of aluminum which is easier for installation and removal.åÊSee detail view here.

Weight Comparison
One-piece 25.5 lbs.
Two-piece 23.5 lbs.
Weight Savings: 2 lbs.

  2. The center-mount flanges for hat mounting to the rotor ring have several benefits. (Illustration #2)
  • It allows the ring to be used on either side of the vehicle simply by mounting the hat on either side of the ring (unidirectional).
  • The stress load transferred from the ring to the hat is balanced.
  • Air inlets are widely open to both inboard and outboard sides of the rotor. More air suctions and even temperature on both sides of the disc surface.
  • Heat transfer from the disc surfaces to the hat is even and minimized by increasing the flange length and the airflow around the flanges.
  • Mounting flanges are on both friction surfaces ultimately provides excellent heat balance.
  • Exclusive full floating design with 10.9 grade alloyed hardware. Hardware is DACRO coated and crimp locking. DACRO is highly corrosion resistant and provides a film for easier movement between the hat and rotor ring as disc expands and contracts and the crimp design provides positive engagement without rattling or torque loss at temperature.
