Got this kit when I purchased my coilovers but I have decided to go a different route. The kit is brand new in box, just opened to make sure everything was there. The description below is from ImportImageRacing where I got this from. Price is $115 shipped. Pm or post any questions etc. Thanks.
“The 08-11 STI requires the Whiteline Rear Camber Adjusting Kit to be able to adjust the rear end camber settings. This kit includes high durometer upper control arm bushings and cam bolts that allow for on car adjustment of +/-.75° of camber (depending on ride height). The increased adjustment will also enable experienced suspension tuners to increase camber for improved handling performance. Sold as a pair.
Part Number: KCA326”
