GiroDisc 97-04 Audi A6/Allroad (C5 w/Alcon/Stoptech 355×32 Rotors) Slotted Front Rings
GiroDisc slotted front rotor rings deliver direct replacement performance for 1997-2004 Audi A6 and Allroad C5 models equipped with Alcon or Stoptech 355x32mm big brake kits. The two-piece construction with high-carbon slotted rings and aluminum hats reduces unsprung weight by up to 40% compared to one-piece rotors while maintaining rigidity under extreme heat. This setup provides consistent pedal feel, fade-resistant braking, and extended pad life for aggressive driving.
Key Features
- Two-Piece Floating Design: High-carbon slotted ring floats on 6061-T6 aluminum hat to handle thermal expansion without warping or cracking.
- Slotted Rotor Surface: Narrow slots enhance initial bite, expel gases and debris for reliable performance in wet or track conditions.
- Curved Internal Vane: Patented 72-vane design directs cooling air through rotor core, dissipating heat 30% faster than straight vane rotors.
- Lightweight Aluminum Hat: Hard-anodized 6061-T6 hat weighs 5.2 lbs per side versus 12 lbs for steel OEM equivalents, lowering rotational mass.
- Precision Dimensions: 355mm diameter x 32mm thickness x 52mm height ensures perfect fit with Alcon/Stoptech calipers and OEM-style hub mounting.
