Alcon ALADIV3430X1052C24L Front Brake Disc Rotor 343mm Two-Piece Vented Left

The Alcon ALADIV3430X1052C24L is a high-performance two-piece vented front brake disc rotor engineered by Alcon, a world-renowned manufacturer of motorsport-grade braking systems. Measuring 343mm in diameter, this rotor is designed to deliver exceptional thermal management and consistent stopping power under demanding track-day and performance driving conditions.

Alcon's two-piece rotor construction pairs a lightweight alloy bell (hat) with a high-grade cast iron friction ring, reducing unsprung weight while allowing for independent thermal expansion — minimizing the risk of disc distortion and cracking under extreme heat cycles. The internally vented design promotes efficient airflow through the disc, drawing heat away from the friction surface for sustained braking performance lap after lap.

Key Features:

• 343mm diameter vented front brake disc
• Two-piece construction — alloy bell with cast iron friction ring
• 24-vane internal ventilation for superior heat dissipation
• Left-hand (L) designation — sold individually
• Designed for motorsport, track-day, and high-performance street applications
• Engineered to OEM and motorsport fitment tolerances
• Manufactured by Alcon to ISO and motorsport quality standards

Alcon brake components are trusted by professional racing teams and performance enthusiasts worldwide. The ALADIV3430X1052C24L front rotor is built to perform where standard OEM rotors fall short — delivering race-proven reliability in the most demanding braking environments.
