Q & A
What's in the Box
5/8" Studs Installed - All coarse threads are quick start style.
Our new 10" hybrid rotor is designed to fit the Pinto spindle. Complete with inner and outer races and 5/8" studs. Pre-drilled holes include 5 on 5" bolt circle spacing.
This brake rotor is designed for dirt track applications and should NOT be used for asphalt racing.
Proper Break-In Procedure for Steel or Cast Iron Rotors
New steel/iron rotors should be bedded in before being used in racing conditions. Proper bedding will prepare the rotor surface, prolong the rotor's life, and make it more resistant to thermal checking or cracking under severe braking conditions. The following procedures should be performed when bedding in both steel and cast iron rotors. It is best to bed in a new rotor using a used set of pads, preferably ones which will not create heat rapidly. Generating heat too rapidly will thermal shock the rotors. Likewise, when bedding in a new set of brake pads it is best to perform the process on a used rotor. This new/used bedding process permits controlled bedding of each individual component.Make sure rotor surfaces are free from oils, grease, and brake fluid. Run vehicle up to a moderate speed and make several medium deceleration stops to heat up the rotor slowly. This will help reduce the chance of thermal shock caused by uneven heating of the rotor. Pull into the pits and allow the rotor to cool to ambient air temperature. Care should be taken not to ride the brakes into the pits as this may hot spot the rotor causing premature wear to the surface or structural damage.

This bearing and seal kit includes two inner wheel bearings, two outer wheel bearings and two inner grease seals. This kit is enough for two brake rotors and is intended to be used with a new rotor installation as this kit does not include the bearing races or cups.
If your project willl be making use of used rotors, you will require new bearing races or cups. Therefore you will need to purchase the bearing and seal kit # 910-31052 suggested below in place of kit # 910-31000.
Works with Mustang II/Pinto and Granada rotors using Mustang II/Pinto spindles only. It will not work for installing Mustang II/Pinto brake rotors on 1949-1954 Chevy spindles. Not for use with early Chevy spindle brake conversion kits.

This brake rotor combines the strength of a '75-'81 Ford-style hub (Granada) with the lighter design of the metric brake rotor for an unbeatable lightweight and durable package. AFCO engineers designed this rotor with the latest CAD software and testing methods. Manufactured to withstand rigorous racing environments, the AFCO Hybrid Rotor uses totally new castings designed and built specifically for racing. It will remove up to 12 lbs. of sprung weight on the front of your car to improve front to rear weight bias and wheel control.
