Bring smooth, balanced braking back to the front axle with the DYNAMIC FRICTION brake rotor 900-73078 (also written 90073078). This front disc brake rotor is a direct-fit replacement for the listed Audi applications: the 2019 and 2021-2026 A8 Quattro, 2017-2026 Q7, 2019-2026 Q8, 2019-2025 A6 Quattro, and 2019-2025 A7 Sportback — see the Buyer's Guide tab for engine-level fitment.

  • Mill-balanced: 100% precision mill-balanced, designed for smoother stops and reduced vibration.
  • Iron casting: made with premium G3000/G11H18 iron castings for strength, stability, and durability.
  • Tight tolerances: disc thickness variation (DTV) held to 0.010 mm maximum and lateral runout to 0.050 mm maximum.
  • Fine-turned finish: 16 RMS fine-turned surface for improved initial rotor and pad break-in.
  • Geomet® coated for high-performance corrosion protection, with an original equipment (OE) vane configuration to support proper heat dissipation.

The rotor provides the friction surface the front brake pads clamp against to slow the wheel. If worn, scored, or warped rotors are behind pedal pulsation, vibration under braking, or reduced stopping feel, this replaces them. Replace both front rotors as a matched pair for even, balanced braking.

Frequently Asked Questions

What vehicles does the DYNAMIC FRICTION brake rotor 900-73078 fit?

It fits the 2019 and 2021-2026 Audi A8 Quattro, 2017-2026 Q7, 2019-2026 Q8, 2019-2025 A6 Quattro, and 2019-2025 A7 Sportback. See the Buyer's Guide tab for engine-level fitment.

Is this a front or rear rotor?

It is a front brake rotor, cataloged for the front axle on the listed Audi applications.

What is this brake rotor made of?

It is made with premium G3000/G11H18 iron castings for strength, stability, and durability, with a Geomet® corrosion-protection coating.

What are signs my front rotors may need replacing?

Pedal pulsation, vibration under braking, scoring, grooves, or reduced braking feel can be signs. Diagnose the cause first, since these symptoms can have other sources.

Should I replace both front rotors at once?

For even, balanced braking it is best practice to replace both front rotors together as a matched pair rather than one side alone.
