Yeah I've got it. Well it came with the car, It's a manual adjusted tensioner instead of spring loaded so you have to make sure it's set up right.
I've got the one with just the brackets and the belts, not the billet pulleys and stuff but it's a fair bit for just is what's essentially a bracket!!
Couldn't comment on how much of a change it is as when it was fitted there was also other things done (flywheel, belts, dephaser, the works). Revs freely though and was definitely quicker after it was removed. (I knew the car before it became mine)
Weight saving is good, also means the front end could be taken off without having to worry about the AC gas, haven't had it long enough to comment on whether I miss the AC but I'd rather go quicker than be cool
