Product Details
Raybestos 581043 is a coated, vented front rotor engineered around the dimensions required for specific Cadillac brake packages. The 300 mm outside diameter, 26 mm nominal thickness, and 5-bolt mounting pattern make it a direct-fit option for vehicles that use the JE5 brake code or the listed non-Brembo, non-slotted configurations. This rotor is a practical choice for Cadillac ATS front brake service and Cadillac CT4 front brake replacement where the original rotor dimensions match the application.
The Specialty - Street Performance line focuses on rotor fit, finish, and braking consistency for daily-driven performance vehicles. This Raybestos 581043 rotor also cross-references Centric Parts 121.62136 and PowerStop AR82159EVC for the same application.

Installation Notes
Verify rotor diameter, center hole diameter, bolt circle, and brake package before installation. This rotor is for front axle use only and is not listed for Brembo-equipped ATS models or slotted-rotor applications where excluded in the fitment notes. Clean the hub mounting surface before installing to help prevent rotor runout and pedal pulsation.
Quality Assurance
Raybestos manufactures this rotor to match the specified OE-style dimensions and application requirements for Cadillac ATS and Cadillac CT4 front brake service. The coated finish helps protect non-friction surfaces from corrosion during normal use and storage.
