Overview
The Baer Brakes 6910186 is a left-side, 2-piece replacement rotor ring with an 11.625 inch outside diameter and a 0.705 inch nominal thickness. Its surface is slotted, drilled and zinc-plated, and it is sold individually. It is made for certain Baer SS4 Plus Deep Stage systems and other Baer Brake systems.
This is a vented cast iron ring with full two-piece construction. It has a curved vane design for cooling and is dynamically balanced. The 12-hole mounting pattern on a 7.50 inch circle is the main measurement to compare when checking a Baer SS4 Plus Deep Stage setup against the parts you already own.
Key features
- Two-piece ring design rather than a single-piece rotor
- Slotted, drilled and zinc-plated friction surface
- Curved vane pattern that Baer says supports cooling
- 12 mounting bolt holes on a 7.50 inch bolt circle
- Directional ring made for the left side only
Ring and hat pairing
A two-piece rotor separates the friction ring from the hat, so the two parts must be matched as a set. The ring bolts to the hat through the mounting holes, and the hat carries the bearing and hub connection. Mismatched bolt counts or circle diameters will not seat correctly, so the ring should be verified against the hat before any other work begins.
Because the ring and hat are replaced separately in some setups, inspect both during any brake service. Look at the hat for cracks near the bolt holes, and check that the ring sits flat with no movement once tightened. Clean the mounting faces before assembly so debris does not change the seating.
- Confirm the hat pattern before ordering
- Check mounting holes for cracks or elongation
- Clean both mating faces before assembly
- Tighten fasteners in a star pattern

Vehicle fitment
No vehicle year, make or model is tied to part 6910186. It is made for certain Baer SS4 Plus Deep Stage and other Baer Brake systems, so compatibility depends on the system.
Confirm your vehicle’s year, model and trim before ordering. Baer’s own specifications for the SS4 Plus Deep Stage setup show the ring and hat pairing to check.
Installation notes
Because this ring is directional and left-specific, confirm the side before assembly. The 12-hole, 7.50 inch bolt circle must match the hat it mounts to, so check that pattern first. The surface is slotted and drilled, so inspect the holes for debris before it goes in.
What’s included
One left-side 2-piece replacement rotor ring, Baer Brakes part 6910186.
Not included: the opposite-side ring and the hat the two-piece ring attaches to, plus brake pads, calipers and hardware.
