Product Details

This DFC brake rotor is built for rear right Ford Mustang brake service where a vented, drilled, and slotted rotor is specified. The directional surface helps maintain consistent pad contact, while the plain disc finish and zinc silver hat finish support a clean, corrosion-resistant appearance. The 300 mm outside diameter, 35.2 mm overall height, and 5-lug 114.3 mm bolt circle match the listed Mustang rear brake applications for 2005-2014 models. Part number 631-54058R is a direct-fit disc brake rotor for the rear right position on the Ford Mustang.

Common Reasons To Replace

• Brake pulsation from rotor wear or thickness variation
• Visible scoring, grooves, or heat checking on the braking surface
• Corrosion on the rotor hat or braking surface
• Reduced braking consistency during normal street driving
• Rotor thickness approaching discard specification

Installation Notes

Verify rear right fitment against the vehicle’s brake package before installation, especially on 2011-2014 Ford Mustang models with standard brakes or Performance Brake configurations. Confirm rotor dimensions, bolt pattern, center hole diameter, and thickness specifications before service. Always inspect pads, caliper hardware, and hub condition during rotor replacement, and follow the vehicle manufacturer’s torque and bedding procedures.

Quality Assurance

Dynamite Friction identifies this rotor by part number 631-54058R and specifies a rust-resistant coating with a zinc silver hat finish for corrosion protection. The directional drilled and slotted design, vented construction, and published dimensional data provide the key reference points for verifying the correct rear right Ford Mustang brake rotor before installation.
