GiroDisc 08-16 Audi S4/S5 (B8) Slotted Rear Rotors

GiroDisc 08-16 Audi S4/S5 (B8) Slotted Rear Rotors are two-piece performance brake rotors built for the rear position on B8 platform vehicles from 2008 to 2016. These 330mm diameter slotted rotors enhance heat management and provide reliable stopping power under demanding conditions. The lightweight construction cuts unsprung mass for sharper handling.

Key Features

  • Two-Piece Construction: 6061-T6 forged aluminum hats paired with high-carbon cast iron rings reduce rotational mass by 4.5 lbs per pair versus OEM
  • Slotted Surface: Narrow slots clear gases and debris for stronger initial bite and fade-resistant performance during repeated hard stops
  • Curved Vane Design: Internal vanes direct cooling air through the rotor improving thermal capacity for track or street use
  • Floating Interface: Bobbin-mounted rings expand independently of hats to resist warping and maintain flatness
  • Direct Bolt-On Fit: Matches OEM 330mm x 25mm x 68mm dimensions no modifications or adapters required

Product Notes

  • Sold as complete left and right rotor pair
  • Compatible with OEM calipers pads and hardware
  • Heavy item requires sturdy packaging for safe transit
