R1 Concepts Disc Brake Rotor Set

This wheel spacer is designed for vehicles requiring a 5x112mm bolt pattern and a 66.50mm hub bore. It is compatible with the 1999 Audi A6 Quattro (C5 generation, 1997-2005) which commonly features these specifications. The optimal offset for the Audi A6 Quattro varies based on wheel width and original equipment, typically ranging from ET30 to ET47. This product is suitable for vehicles originally equipped with 15-inch wheels and other wheel sizes that adhere to the specified bolt pattern and hub bore. Specific fitment may vary based on individual vehicle modifications and desired wheel aesthetics. For optimal fitment, it is recommended to cross-reference the bolt pattern, hub bore, and desired offset with your vehicle's current setup.
