DFC Brake Rotor Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line focuses on rotor geometry and corrosion protection for European vehicle brake systems. On this application, the black hat finish and coated surface help maintain a cleaner appearance while the slotted and drilled face supports consistent pad contact characteristics.

Detailed Description

This Dynamite Friction rotor is engineered for rear left installation on a wide range of Audi and Porsche models, including Audi A4 allroad, A5 Sportback, A6 Quattro, Q5, S4, S5, SQ5, and Porsche Macan applications. The rotor uses a directional, slotted X drilled braking surface and vented design to match the fitment and brake package requirements listed for these vehicles. With a nominal thickness of 21.9 mm and discard thickness of 20 mm, it is specified for direct replacement service where the listed dimensions and bolt pattern match the original equipment setup.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Brake pulsation caused by worn or uneven rear rotor surfaces
• Corrosion on exposed rotor hats and braking surfaces
• Reduced braking consistency from heat-affected rotor faces
• Noise or pad contact issues related to rotor wear
• Service replacement needs on Audi and Porsche rear left brake systems

Installation Notes and Tips

Verify rear left fitment by matching the 330 mm outside diameter, 68 mm center hole diameter, 112 mm bolt circle, and listed vehicle notes before installation. Several applications depend on caliper type, front brake package, or production date, so confirm the exact vehicle configuration for your Audi A4 allroad, Audi A5, Audi A6 Quattro, Audi Q5, Audi S4, Audi S5, Audi SQ5, or Porsche Macan.

For best results, inspect pads, caliper hardware, and hub condition during rotor replacement. Clean the hub mounting surface thoroughly so the rotor seats flat and the directional surface is oriented correctly on the rear left side.

Quality Assurance

Dynamite Friction manufactures this rotor with a rust resistant coating and zinc black hat finish for corrosion protection and long-term appearance retention. Part number 633-73066L is built to the dimensional and fitment specifications listed for the confirmed Audi and Porsche rear left applications.
