Bringing this thread back. I think I have found what can be allowing the wheel-hop. The strut mounts have a decent amount of movement, though they are only a year or two old (They had this movement since they were new).
Does anyone know of strut mounts with harder rubber? To minimize movement. The ones I have are Monroe.
I'm thinking the mount is acting like an rubber band, letting the wheels bounce undamped. The video doesn't show the full amount of movement.
