Why Audi A4 / S4 Brakes Need an Upgrade

Factory brakes on the Audi A4 / S4 are engineered for normal street driving — moderate speeds, light loads, and occasional hard stops. Push beyond that envelope with track days, towing, off-road use, or repeated spirited driving, and pad fade, rotor warp, and excessive dust become the limiting factors.

Ghost Rotors addresses all three failure modes with a matched rotor-and-pad system: drilled and slotted rotors for heat evacuation, GEOMET coating for corrosion resistance, and carbon ceramic pads for stable friction under heat and 60% less dust than OEM.

What's in the Ghost Rotors Audi A4 / S4 Kit

  • G11H18 1-piece drilled and slotted rotors (front and rear)
  • Carbon ceramic brake pads — matched compound for our rotor face
  • GEOMET full-surface corrosion coating

  • Free shipping

Installation and Bedding

Ghost Rotors Audi A4 / S4 kits are direct bolt-on replacements for factory rotors and pads. Install using standard hand tools — no caliper modifications or brake line changes required.
