EBC S12 Brake Pad and Rotor Kit - S12KR1577

The EBC S12 Brake Pad and Rotor Kit (S12KR1577) pairs EBC's Redstuff brake pads with RK OE-style replacement rotors in a rear-axle kit engineered for the 2016-2019 Audi Q3 and Q3 Quattro. This complete two-wheel kit gives Q3 owners a straightforward way to replace worn rear pads and rotors together with matched, ready-to-install components rather than sourcing pads and rotors separately.

Key Features & Benefits

• Complete rear kit — Redstuff brake pads and RK rotors are matched and sold together, simplifying your rear brake service into a single order.
• Solid rotor design — the RK rotor in this kit is a solid (non-vented) design built to OE-style dimensions for a factory-like fit and pedal feel.
• Correct FMSI cross-reference — pads carry FMSI pad number D1779, helping confirm you're getting the correct pad shape and application for your Q3's rear calipers.
• Precise rear-axle fitment — sized to the specific bolt pattern and rotor dimensions of the Q3 rear brake system, reducing guesswork during install.
