The AP Racing ventilated brake discs have been designed with the high demands of the Motorsport world in mind. Constructed from high-quality materials and utilising the extensive knowledge gained through a constant development programme, these discs are engineered to perform at the highest level.

Each disc undergoes rigorous in-house testing on a dynomometer and track testing to ensure optimal performance. The AP Racing product line includes both bolted and floating discs with various face types.

Disc Face Types

• P - Plain: Mainly used for road applications where road noise is preferred.
• G4, 8, 12, 24 - Grooved (Straight, forward facing): Traditional style straight grooves. The number signifies the number of grooves on the disc face.
• CG4, 8, 12, 24 - Curved Groove (Backward facing): A standard grooved pattern with backward-facing grooves. The number signifies the number of grooves on the disc face.
• CR4, 8, 12, 24 - Curved Groove (Backward facing running to the edge of the disc diameter): Ideal for clearing debris from the disc face. The number signifies the number of grooves on the disc face.
• D - Cross Drilled: The drilled holes are chamfered with holes spaced across the face of the disc in lines. Still preferred by some pad materials but can compromise the disc life.
• GD - Grooved and Drilled: Usually used for road applications.
• RD - Radius Drilled: The same as cross-drilled but with a radiused run out to the edge of the disc, reduced noise and improved life when compared to standard drilling patterns. Mainly used for aesthetic reasons on road applications.
• RA - J-Hook Design: The outer grooves run out to the edge of the disc face, used on thick wall discs only. This pattern gives improved bite and debris clearance, it also reduces distortion or vibration.
• GA - J-Hook Design: The same as the RA type but the outer groove does not run to the edge of the disc. Improved bite and debris clearance combined with reduced distortion or vibration.
• RC - J-Hook Design: The same as the RA type but has 3 hooks across the disc face. Designed for thick wall discs only.

Please note that not all face types are available for each disc.
