The pulley was not that difficult to remove/install but I wouldn't recommend it to anyone as the gains are really not there and I have some paranoid concerns regarding the harmonic dampner that is on the OE pulley. I dunno, I just don't think it's a worthwhile mod w/ some many other things out there that are clearly worthwhile. I did notice that A/C clicking noise when the compressor is switching on is a bit louder and the lights do dim when idling w/ my pulley.

The sway bar is a good mod if you autocross or do any type of track driving but I would skip this if you only drive the car on the street as I doubt you will/should be pushing the car hard enough to notice or care much. This mod can make your car handle dangerously if you are not prepared(ie: driven the crap out of it on controlled track and know what to expect). The bar with the middle setting on my car makes things pretty scetchy off the pavement, scared the living crap out of my passenger.
