Developed as an evolution of the Project Kics Racing Composite R40/R40 REVO type, the R40 iCONIX Lock & Nut Set (Resin Caps) features an improved screw-type through-hole and cap nut design, allowing for easy installation and removal with a dedicated wrench even when the wheel is installed. The unique design, with six holes drilled into the hex face to reveal the end cap, makes it a stand-out piece that accentuates the wheel. The main nut is forged from SCM435 and comes in two colors: black and neo-chrome. Each floating collar is available in three colors (red, blue, or black) to match the cap color.
