Dynamic Friction 631-65020L Disc Brake Rotor - Rear Left

Overview

The Dynamic Friction 631-65020L is a vented disc brake rotor with a slotted and drilled surface, built for specific Saab applications that require a rear left rotor. It combines a zinc silver hat finish with a rust-resistant coating for added surface protection and a cleaner appearance.

Compatible With Saab 9-3 and Saab 9-3X applications, this rotor is identified by part number 631-65020L and is engineered for directional brake surface operation. The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor design details that matter for braking consistency and corrosion resistance.

Key Features

• Slotted and drilled braking surface for improved pad contact characteristics.
• Vented rotor construction for heat management during repeated stops.
• Zinc silver hat finish with rust-resistant coating.
• Directional brake surface design.
• 5-lug pattern with 110 mm bolt circle and 70 mm center hole.

Detailed Description

This Dynamic Friction brake rotor is a direct-fit style replacement for listed Saab 9-3 and Saab 9-3X rear left applications. The 292 mm outside diameter, 20 mm nominal thickness, and 18 mm discard thickness provide the dimensional profile needed for the specified fitment, while the slotted X drilled surface supports consistent pad interaction. The part number 631-65020L should be verified against the vehicle’s brake package before ordering, especially on Saab 9-3 models with the performance package or 345 mm front disc brake notes listed in the fitment data.

The DFC Brake Rotor - Drilled and Slotted - Silver line is positioned around rotor surface engineering and corrosion protection. For Saab 9-3 and Saab 9-3X owners looking for a rear left brake rotor with a vented design and protective finish, 631-65020L matches the listed application details.

What It Is Used For

• Replacing a worn or scored rear left brake rotor.
• Addressing brake pulsation caused by rotor surface variation.
• Restoring braking performance when rotor thickness is near discard limits.
• Reducing visible rust on exposed rotor surfaces.

Installation Notes and Tips

Confirm the rear left position, 5-lug bolt pattern, 110 mm bolt circle, and 70 mm center hole before installation. Review the vehicle notes carefully for Saab 9-3 performance package and 345 mm brake package references, since the fitment data is specific to those configurations. Always compare the old rotor dimensions and part number 631-65020L to the vehicle specification before service.
