Detailed Description

Centric Premium Disc Brake Rotors are part of the Centric Premium Disc Brake Rotors line, which focuses on replacement rotors with corrosion-resistant finishing and OE-style fitment details. This rotor uses an electrocoating finish rather than a basic phosphate coating, giving the exposed metal surfaces stronger protection against rust after installation. The rear rotor design for the Porsche 944 includes a vented construction, straight vane layout, 103 mm center hole diameter, and 130 mm bolt circle to match the specified application.

Use part number 120.37026 when searching for a rear brake rotor for Porsche 944 models from 1987 through 1989. This part also cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Rust buildup on the rotor hat or exposed braking surfaces
• Reduced braking consistency from worn rear rotors
• Noise from uneven rotor surfaces during pad contact
• Service replacement for a damaged or out-of-spec rear rotor

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub center diameter before installation on your Porsche 944 rear brake system. Clean the rotor and hub mating surfaces before mounting, and inspect brake pads, caliper condition, and wheel bearings during service. Confirm that the rotor thickness remains above discard specifications after installation and bedding.

Quality Assurance

Centric premium rotors use an electrocoated finish designed to resist corrosion far beyond basic storage coatings. The finish is engineered to withstand extended salt-water exposure testing, helping preserve the rotor’s appearance and surface protection after installation.
