Description

These Vented Discs from AP Racing have been designed with the high demands of the Motorsport world in mind. Made from high quality materials, and using their wealth of knowledge and experienced gained through of a constant development programme, these discs are designed to perform at the highest level.With a huge range of sizes available, there are discs available for almost every Motorsport application (see the disc sizing information at the bottom of the page to make the correct selection). Each disc benefits from in-house testing on a dynomometer and track testing. Included in the range are both bolted and floating discs with varying face types. These types are detailed below.Disc Face TypesP = Plain - Mainly used on road applications where road noise is required.G4, 8, 12, 24 = Grooved (Straight, forward facing) - Traditional style straight grooves. The number signifies how many grooves are on the disc face.CG4, 8, 12, 24 = Curved Groove (Backward facing) - This is a standard grooved pattern. The number signifies how many grooves are 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 how many grooves are 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 with some pad materials but can compromise the disc life.GD = Grooved and Drilled - Usually used on 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.Note: Not all face types are available for each disc.AP Racing 300-355mm Disc Dimensions
