Verus Engineering UCW Rear Wing KitThe UCW rear wing is a great addition to your VA WRX to increase downforce significantly in the rear, increase confidence on track, and reduce lap times. Verus Engineering developed the UCW rear wing to bridge the gap between our swan neck high efficiency rear wing and our 300mm V1X airfoil. With the 250mm curved chord, the UCW makes more downforce than the high efficiency rear wing and significantly more downforce than similarly sized competitor
