Galfer Racing brake disc - For Honda CBR 1000 RR-R SC82

GALFER Racing brake discs DF134JCW163 – 330 mm / 6.3 mm

Price for 2 brake discs (set)

The Galfer DF134JCW163 Racing brake discs are high-performance, next-generation brake discs designed for professional use on the racetrack. With a diameter of 330 mm and a particularly robust 6.3 mm material thickness, they offer maximum stability, consistent braking power, and outstanding heat resistance, making them ideal for modern superbikes and racing machines.

The discs are made from a high-alloy steel compound with optimized thermal conductivity, combined with the precise Galfer Racing grinding pattern, which ensures rapid heat dissipation, excellent pad cleaning action, and consistent performance. The floating design (JCW) guarantees the best possible feedback control and prevents warping even under extreme racing conditions.

Key features

• Racing brake disc 330 mm – maximized braking power and higher thermal capacity
• Material thickness 6.3 mm – for high stability and maximum heat resistance
• JCW Floating System – precise guidance, minimized distortion, perfect centering
• High-quality steel alloy for better temperature conduction and durability
• Optimized friction surface for stronger bite and less fading
• Designed for professional racing
• Compatible with Galfer Racing brake pads such as G1310 for best results

Advantages of a 6.3 mm thick racing brake disc

A 6.3 mm racing brake disc offers several clear advantages over conventional 5–5.5 mm brake discs:

1. Higher thermal capacity

More material means the disc can absorb more heat without overheating.
→ Less fading, more stable braking performance even during long stints.

2. Less delay in hot weather

Thicker material is stiffer and more resistant to heat deformation .
→ The disc retains its shape even at high temperatures and during aggressive braking.

3. Longer lifespan

Greater thickness = greater wear reserve:
→ Can be used for longer, remains within the optimal tolerance range over many race weekends.

4. Improved dosing capability

The stiffer disc creates a more precise, direct braking feel at the lever.
→ Especially important for later, sensitive braking on the racetrack.

5. Perfect for heavy-duty racing brake pads

Heavy-duty brake pads like Galfer G1310 or Brembo Z04 deliver their full performance on a thicker disc, as this can better withstand mechanical and thermal stresses.

Conclusion

The Galfer DF134JCW163 330 mm / 6.3 mm is an uncompromising racing brake disc for riders who demand the highest braking performance, maximum stability, and absolute reliability. The 6.3 mm version offers noticeable advantages in heat resistance, modulation, and durability, making it ideal for modern superbikes in demanding racing conditions.
