Product Details

The Alcon DV304/28/55-12/178R is a direct vane ventilated brake disc from Alcon's renowned Pro-System motorsport brake range. Engineered for high-performance and competitive motorsport applications, this rotor delivers consistent, fade-resistant braking performance under sustained heavy use.

Alcon's direct vane design promotes efficient heat dissipation through the rotor's internal vane structure, reducing thermal buildup during repeated hard braking. The rotor is directional — the R (Right) suffix denotes this disc is designed for right-hand fitment to ensure optimal airflow direction through the vanes.

Key Specifications:

  • Rotor Outer Diameter: 304mm (11.97 in)
  • Rotor Thickness: 28mm (1.10 in)
  • Hat Height: 55mm (2.17 in)
  • Mounting Bolt Holes: 12
  • Hat Bore Diameter: 178mm (7.01 in)
  • Fitment Side: Right (R)
  • Vane Type: Direct Vane (DV) — ventilated
  • Product Line: Alcon Pro-System

Key Features:

  • Precision-machined to exacting motorsport tolerances
  • Ventilated direct vane construction for superior thermal management
  • Directional design optimizes cooling airflow for right-side installation
  • Compatible with Alcon Pro-System bell and hat assemblies
  • Suitable for track day, time attack, rally, and professional motorsport use

The Alcon Pro-System modular rotor design allows the disc to be replaced independently from the bell/hat, reducing long-term running costs in competitive environments. OEM cross-reference and Alcon manufacturer part number: DV304/28/55-12/178R.

No shop around had the prop I needed. We had plans to fish but I hit a rock. The prop came in time to get back out on the water and get out limit!! Arrived next day!

Look forward in working with your team more in the future.

The only issue was the shipping straps on both shocks were broken on one end only! Made it more difficult to install! But for the price I can't complain much! Thanks

Easy to navigate the ordering process and received the product in a timely manner.

Great service! Gave additional first responder discount
