Dynamic Friction 633-80015L Disc Brake Rotor - Rear Left

Overview

Dynamic Friction 633-80015L is a vented disc brake rotor with a slotted and drilled surface, built for direct replacement applications that require a directional brake surface. The zinc black hat finish and rust-resistant coating add corrosion protection, while the plain disc finish keeps the braking surface consistent.

Key Features

• Vented rotor construction for improved heat management.
• Slotted and drilled surface for more consistent pad contact.
• Zinc black hat finish with rust-resistant coating.
• 5-lug bolt pattern with 114.3 mm bolt circle.
• Directional braking surface for specific fitment requirements.

Detailed Description

This Dynamic Friction brake rotor, part number 633-80015L, is engineered with a vented design and a directional slotted-and-drilled braking surface. It measures 273 mm in outside diameter, 53 mm in overall height, and uses a 66 mm center hole diameter with 12.4 mm stud or lug holes. The rotor is specified with 20 mm nominal thickness and 18 mm discard thickness, giving buyers the dimensional details needed for service matching. For Mazda RX-7 applications, this rotor is listed for rear left fitment on 1989-1991 models and on 1986-1988 models with 5-lug wheels.

DFC Brake Rotor - Drilled and Slotted - Black is the product line designation, and it identifies a rotor family focused on drilled-and-slotted braking surfaces with a black-coated hat for added corrosion resistance. The part number 633-80015L is also useful when verifying the correct rotor against catalog listings or service records. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a worn rear brake rotor with the correct directional design.
• Addressing rotor surface wear that can affect braking feel.
• Restoring proper brake contact on vented rear rotor applications.
• Matching a 5-lug, 114.3 mm bolt circle rotor specification.

Installation Notes and Tips

Verify rotor thickness, center hole diameter, and bolt circle before installation. Confirm rear left placement and match the directional surface orientation to the vehicle side. For Mazda RX-7 fitment, check whether the vehicle uses the 1986-1988 5-lug wheel configuration or the 1989-1991 vented rear rotor application. Use part number 633-80015L to confirm catalog accuracy during ordering and service lookup.

Quality Assurance

Dynamic Friction supplies this rotor with a rust-resistant coating and zinc black hat finish for added surface protection in service.
