Overview
A left-side, 1-piece replacement brake rotor with a modified drum in the hat, made for select Baer Brake systems. It is a vented cast iron rotor with a slotted, drilled and zinc-plated surface.
At 12 in outside diameter and 1.02 in nominal thickness, it has a 3.065 in center hole and an overall height of 2.406 in. The rotor is directional and made for the left side of the vehicle only.
Key features
- Drum in hat with a modified drum
- Slotted, drilled and zinc-plated surface
- Curved vane design intended for cooling
- Full cast, one-piece construction
- Dynamic balancing for vibration-free performance
- Five studs on a 4.75 in circle
Drum and hat clearance
A modified drum in the hat changes how the rotor sits on the hub and how much room the caliper and wheel have behind it. Before fitting, check that the hat seats flat against the hub face and that the drum does not contact the bearing or spindle. Any change in hat geometry can affect runout, so measure runout after mounting.
Slotted, drilled and zinc-plated rotors are often used in performance setups, where heat and wet conditions can be harder on the braking system. Pads should be chosen to suit the rotor surface, and the pads, lines and calipers should be inspected when the rotor is replaced. Keep the left-side rotor paired with its matching right-side unit.
- Confirm hat seating and drum clearance before final assembly.
- Measure runout after the rotor is bolted on.
- Inspect calipers and brake lines during the job.

Vehicle fitment
It is made for select Baer Brake systems. Confirm fit for your vehicle’s year, model and trim before ordering.
Match the 12 in diameter and 3.065 in center hole to your Baer application before ordering.
Installation notes
The modified drum in the hat is a specific detail, so confirm it suits your application before fitting. Rotors are sold individually, so a pair needs a matching right-side unit. Brake work is safety-critical, so a qualified technician should complete the installation.
