Back when I was "wheel-hunting" I came across these and thought they would look good on an IronMan VX:

JDM JAOS Victron Wheel (Victron Excel II Pro 16X8 Offset 0) "White"

Unfortunately...they are pricey...$478.72 per wheel plus shipping ($23) at this site...maybe find them cheaper somewhere else?
