Product Details

Centric Premium OE Style Slotted Disc Brake Rotors are engineered with an electrocoating finish that resists corrosion far beyond basic phosphate coatings. Centric states the E-coat finish is designed to withstand up to 400 hours of salt water exposure without rusting, helping preserve the rotor during service and after installation. This rotor measures 330 mm in outside diameter, 28 mm nominal thickness, and 26 mm discard thickness, with a vented construction and curved vanes for stable braking performance.

Use this rotor on select Porsche 911 rear left applications, including 2001-2005 Porsche 911 rear left, 2007-2010 Porsche 911 rear left, 2018 Porsche 911 rear left, and 2019-2020 Porsche 911 rear left. It also fits 2010-2013 Porsche Panamera rear left. The part number 126.37040 is also referenced in OE-style brake rotor searches for Porsche rear axle service.

This part cross-references Centric Parts 226.37040 and Raybestos Brakes 980827 for the same application.

Common Problems This Rotor Helps Address

• Rear brake rotor wear on Porsche 911 and Porsche Panamera models
• Surface corrosion on exposed brake rotor hats and braking surfaces
• Brake fade from heat buildup during repeated stops
• Uneven pad contact caused by worn or damaged rotor surfaces
• Noise or vibration associated with rotor wear beyond service limits

Installation Notes and Tips

Verify rotor thickness, hub fitment, and rear left application before installation. This rotor uses a floating/DIH mounting type, a 5-lug pattern, and a 98 mm hub hole diameter, so matching the vehicle’s original brake setup is important. For best results, inspect pads and caliper condition at the same time and confirm the rotor is within service specifications before returning the vehicle to service.

Quality Assurance

Centric Premium rotors use an electrocoated finish for corrosion protection and are built to OE-style dimensional standards for the listed Porsche applications. The slotted, vented design and coated hat finish support consistent service life in demanding driving conditions.
