Dynamic Friction 633-02002L Disc Brake Rotor - Rear Left

Overview

The Dynamic Friction 633-02002L is a vented, slotted and drilled brake rotor built for Porsche 911 rear left applications. It combines a directional brake surface with a black zinc hat finish and rust-resistant coating for a clean, service-focused replacement.

Compatible with Porsche 911 fitments from 1969-1983, this rotor is listed for multiple caliper and package configurations. The 633-02002L is a fitment-specific choice for owners replacing a rear left disc brake rotor on classic Porsche 911 models.

Key Features

• Slotted X drilled surface for consistent rotor face engagement.
• Vented rotor construction for improved heat management.
• Black zinc hat finish with rust-resistant coating.
• Directional brake surface for application-specific rotation.
• 5-lug pattern with 130 mm bolt circle diameter.

Detailed Description

Dynamic Friction 633-02002L is a disc brake rotor engineered around the dimensions and mounting pattern used on Porsche 911 rear left applications. The rotor measures 290 mm outside diameter with an 83 mm overall height, 90 mm center hole diameter, and 5 stud/lug holes on a 130 mm bolt circle. Its plain disc finish is paired with a slotted X drilled braking surface and vented construction to support stable braking performance under repeated use.

The DFC Brake Rotor - Drilled and Slotted - Black line focuses on corrosion resistance and application-specific fitment. On this part, the zinc black hat finish and rust-resistant coating help protect exposed surfaces, while the directional design matches the listed Porsche 911 configurations. Part number 633-02002L appears across the fitment data for 1969-1983 Porsche 911 rear left applications, including versions with vented rotors and several caliper setups. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a worn rear left brake rotor on a Porsche 911.
• Addressing rotor scoring, grooves, or uneven braking feel.
• Restoring proper braking surface contact on a vented rotor setup.
• Replacing a rotor affected by corrosion on exposed surfaces.
• Matching application-specific caliper and package configurations.

Installation Notes and Tips

Verify the listed Porsche 911 year, caliper type, and package notes before ordering. This rotor is specified for rear left fitment only, and the directional surface must be installed in the correct orientation. Confirm the 130 mm bolt circle, 90 mm center hole diameter, and 5-lug pattern against the existing part before installation.

Quality Assurance

Dynamic Friction identifies this rotor as part of its DFC Brake Rotor - Drilled and Slotted - Black line, with a rust-resistant coating and black zinc hat finish for added surface protection. Part number 633-02002L is cataloged for multiple Porsche 911 rear left applications from 1969-1983.
