Overview
The Baer Brakes 6920078 is a right-side, 1-piece tall hat replacement rotor with slots, drilled holes and a zinc plated finish. It measures 13.000 inch in diameter and 1.100 inch thick, with five studs on a 4.50 inch lug hole circle and a 2.781 inch center hole.
The rotor is directional and made only for the right side. Its cast iron body is vented, and it carries a slotted, drilled and zinc plated surface finish.
Key features
- Slotted and drilled friction face
- Zinc plated finish
- Right-side directional rotor
- Full cast one-piece body in cast iron
- Curved vane layout aimed at cooling
- Balanced dynamically for smooth running
- Performance grade type with emission code 6
Drilled and slotted faces
Drilled holes and slots both give a rotor a way to shed gas and water, but they also create edges where heat stress can concentrate. Over time, cracks may begin at the edges of holes or at the ends of slots, especially in hard use. Inspect these areas at each pad change and look for any crack that runs toward the outer edge of the friction face.
A zinc plated finish is mainly a corrosion barrier for storage and the hat area. The friction face loses that coating quickly during braking, so light surface rust after storage is normal and usually clears with the first few stops. Keep the hub clean and dry, and make sure the mounting surface is free of corrosion before fitting.
- Check drilled holes for cracks at each pad change
- Inspect slot ends for heat checking
- Clean rust from the hub before mounting
- Replace the rotor if cracks reach the friction edge

Vehicle fitment
It is built for certain Baer Track4 and SS4 systems and other Baer Brake setups. Measure the 4.50 inch lug pattern and 2.781 inch center bore on your hub before ordering.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check the right-side marking against the hub before the wheel goes back on, because a directional rotor cannot be reversed. No ABS tone ring comes with this rotor, so use the ring already on the vehicle or add one separately if the setup needs it. Inspect slotted and drilled faces regularly for cracks and wear.
What’s included
One right-side replacement rotor, sold as each. A left-side rotor is a separate item.
Not included: Pads, calipers and any hub hardware are separate purchases.
