DoLuck is a top tier racing and development effort based in Japan. This rear DoLuck underskirt "valance" helps maintain a very efficient and non-turbulent air-flow from underneath the back-end of the car. This very rare piece coupled with the added downforce created with the RMM carbon fiber rear wing provides the ultimate in "air" modification upgrades. The paint color here is not different in color, it is just the angle and the flash that causes a more orange appearance.
