AP Racing Ventilated Brake Discs 300-355mm - 320mm, 4 Curved Grooves, Left Hand, CP3047-406/7

AP Racing's Ventilated Brake Discs, specifically designed for the high demands of Motorsport applications, have been crafted with meticulous attention to detail and a deep understanding of the requirements of top-level performance driving.

These discs are manufactured from premium materials, leveraging AP Racing's extensive experience and continuous development programme to ensure exceptional performance.

Offering an expansive range of sizes, these discs cater to a broad spectrum of Motorsport applications (please refer to the disc sizing information below for accurate selection).

Each disc undergoes rigorous in-house testing on a dynomometer as well as track testing to guarantee optimal results. The comprehensive range includes both bolted and floating discs with various face types, each designed to suit specific needs.

Disc Face Types

• For those seeking a more subtle brake experience, the following face types are available:

• P (Plain): Primarily used on road applications where a more refined braking experience is desired.

• G4, 8, 12, 24: Traditional straight grooves, with the number indicating the number of grooves present on the disc face. These face types provide excellent heat dissipation and are suitable for various driving conditions.

• For drivers seeking enhanced performance and debris clearance, the following curved groove options are available:

• CG4, 8, 12, 24: Standard curved groove patterns with varying numbers of grooves per disc face.

• CR4, 8, 12, 24: Curved grooves extending to the edge of the disc diameter, ideal for clearing debris and maintaining optimal braking performance.

• For those who require additional heat dissipation and improved brake pad compatibility, the following options are available:

• D (Cross Drilled): Chamfered holes spaced across the face of the disc, providing excellent heat dissipation but potentially compromising disc life.

• GD (Grooved and Drilled): A combination of traditional straight grooves and cross-drilling, commonly used on road applications.

• RD (Radius Drilled): Similar to standard cross-drilling but with a radiused run-out, reducing noise and improving lifespan. This pattern is often used for aesthetic reasons on road applications.

• For drivers who demand the ultimate in braking performance and durability, the following J-Hook design options are available:

• RA: Outer grooves extending to the edge of the disc face, providing improved bite and debris clearance while reducing distortion or vibration.

• GA: Similar to RA but with outer grooves not reaching the edge of the disc, offering improved bite and debris clearance combined with reduced distortion or vibration.

• RC: A variation of RA featuring three hooks across the disc face, designed for thick wall discs only.

• Please note that not all face types are available for every disc size. It is essential to consult AP Racing's specifications to ensure accurate selection for your specific application.
