I think the WB flares just look "OK" on the Challenger, but they sure do look great on the Charger. To me, the slab sides and less detail lines and curves of the Challenger just don't lend themselves to the flares as well as the Charger. The Charger has so much more detail lines, curves, scoops, etc, etc, etc, it just looks like the flares should have been on there right from the beginning (of the current body style) JMO
