Project Kics W3066HR Hub Centric Rings 66mm OD 30mm Width (Pair)

The Project Kics W3066HR Hub Centric Rings are a precision-machined accessory designed to ensure a true hub-centric wheel spacer installation. With a 66mm outer diameter and 30mm width, these rings fill the gap between the vehicle hub and the center bore of the wheel spacer, eliminating the lug-centric fit that can lead to vibration at speed. Sold as a pair.

Key Features:

• CNC billet aluminum construction for precision fitment and long-term durability
• 66mm outer diameter fits Japanese vehicle hub bores in the 54mm–67mm range
• 30mm width — compatible with Project Kics Wide Thread Wheel Spacers in that thickness
• Hub-centric design centers the spacer precisely on the hub, reducing wheel vibration at high speeds
• Available across a wide range of sizes (10mm–30mm widths) to suit various spacer thicknesses
• Designed exclusively for use with Project Kics Wide Thread Wheel Spacers
• Sold as a pair (2 rings per package)
