if the bolts are installed in the top hole, it would push the top part of the wheel out when adjusted
if the bolts are installed on the bottom, it would push the bottom part of the wheel out when adjusted
the washer that comes with it has a little tab which takes up the gap in the hole so u can offset the bolt when u turn it...
as my car is lowered slightly, which created a bit of dorrrrift camber, therefor i had mine installed on the top part to make sure i got the wheel back up straight flat (the most contact to the road).. not sure if its the best setting but i guess its good for drag and tyre wear...
if u wanted more doooorift style camber, install it on the bottom hole and offset it there...
Anybody else got any experience with it?
