Got and installed mine today - nice fast shipping from JT. Seemed to make a pretty big difference on my 54,000 mile 04 that's had the damper replaced at least once before (shortly after its first purchase, by a dealer, according to Carfax).
Installation was trivial, and I could have probably done it without jacking the car if I'd wanted. There's no need to remove the splash guard (as I read was necessary in some other threads). A great upgrade for under $30...
