if you can see... the inside of the bolt is kinda humped... so that depending on the possition of the bolt when you tighten it, you can change the possition of the rear upper control arm.
but as you can imagine... there's really not that much adjustment available with it. Its really meant for cars with stock oem suspension. Anyone with lowering springs and coilovers have to have adjustable rear upper control arms like these
but I dont think you have to buy it. IIRC, it should already be in the car... its what the alignment guys touch when you get an alignment. I could be wrong though
