If there's any kit that looks like it belongs on the CH-R, its the first one posted. Design just flows and complements the original design, something very important to factor in. Too many kits these days don't take that into account or at least not in a way to my liking.
Depends on the kit, but there are a lot of statement kits out there that adds on large pieces to make it look forcibly sporty and does nothing for the factory lines. Adding too much to a car like the C-HR, which already has plenty of ridges and sharp angles, would be too much.
