AP Racing Ventilated Brake Discs 254-295mm - 285mm, 8 Grooved, Left Hand, CP3047-276/7

These high-performance brake discs from AP Racing have been engineered to meet the exacting demands of motorsport applications. Constructed from premium materials and benefiting from the company's extensive knowledge and expertise gained through continuous research and development, these discs are designed to deliver exceptional performance.

AP Racing offers a vast range of disc sizes, catering to almost every motorsport requirement (please refer to the disc sizing information at the bottom of the page for guidance on selecting the correct size). Each disc undergoes rigorous in-house testing on a dynomometer and track testing to ensure optimal performance. The product line includes both bolted and floating discs with various face types, which are detailed below.

The selection of disc face type depends on specific requirements, including road applications where noise is a consideration or motorsport applications that demand maximum braking performance. AP Racing offers the following disc face types:

• P = Plain: Primarily used for road applications where a certain level of road noise is desired.
• G4, 8, 12, 24 = Grooved (Straight, forward facing): Traditional straight grooves are featured on these discs, with the number indicating how many grooves are present on the disc face.
• CG4, 8, 12, 24 = Curved Groove (Backward facing): This standard grooved pattern features curved grooves and is denoted by a number signifying how many grooves are present 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, these discs feature curved grooves that run to the edge of the disc diameter.
• D = Cross Drilled: This type features chamfered holes spaced across the face of the disc in lines. While still preferred with some pad materials, it may compromise disc life.
• GD = Grooved and Drilled: Typically used for road applications, these discs combine grooves and drilled holes.
• RD = Radius Drilled: Similar to cross-drilled discs but with a radiused run out to the edge of the disc, reducing noise and improving life. Mainly used for aesthetic reasons on road applications.
• RA = J-Hook Design: The outer grooves on these discs run out to the edge of the face, providing improved bite and debris clearance. This pattern is only suitable for thick wall discs.
• GA = J-Hook Design: Similar to RA type but with the outer groove not running to the edge of the disc, this design offers improved bite and debris clearance combined with reduced distortion or vibration.
• RC = J-Hook Design: Featuring three hooks across the disc face, these discs are designed for thick wall applications only.

Please note that not all face types are available for each disc. It is essential to consult the specific product details before making a selection.
