the wire loom is split, but still in a pretty tight circle, so it fits quite snug-ly on the coil. it is by no means permanent. it really does the trick though, and you dont even have to take the spring off to put the wrap on, cuz thats a pain!!!
as for the ride, yes the ride is bouncier but not too much. you get used to it real quick. i will try to post pics tonight. i really wish i did before and after pics, because it looks so much better now! before, on 205-40-17s, it almost looked like the accord was raised. imho, the looks far outweigh the fact taht the ride is more bouncy. if you have any more questions or if i forget to post pictures pm me.
