Audi S4 Brake Kits

Audi RS and S-line platforms — and BMW M, Porsche, and Mercedes-AMG — demand 2-piece floating rotor architecture for sustained Quattro and track-biased braking. Ghost Brakes 777-XE Euro kits pair G3500 rotor rings with GEOMET-coated aluminum hats and Euro Performance pads for low dust on premium wheels, OEM caliper compatibility, and repeatable hard-stop confidence.

Drilled & slotted GEOMET rotors and matched performance pads for every Audi S4 year and trim. Select your configuration below to compare Economy, GEOMET, Drilled & Slotted, and 2-Piece floating tiers with pricing.

Common Questions

Do Audi S4 and RS5 kits fit factory calipers?
Yes — Ghost Brakes Euro kits match OEM rotor diameter and caliper mounting for each Audi chassis. Select exact year and trim in the vehicle finder.
2-piece only or drilled & slotted 1-piece for Audi?
High-performance Audi RS and track-focused S-line builds typically use 777-XE 2-piece floating rotors. Daily S-line drivers may also see 555 Euro drilled & slotted options where catalog fitment exists.
Will Euro pads reduce brake dust on alloy wheels?
Euro Performance and carbon ceramic compounds produce far less dust than OEM semi-metallics — a common upgrade motivator on Audi, BMW, and Porsche daily drivers.
