For the adjustment of GLA front camber angles:
The dots are NOT camber angles!
Since different ride heights give different camber angles, we simply created a set of camber arms that offer more camber angles than Stock arms.
Stock Arm (least negative camber  - longest arm)
4 dots
3 dots
2 dots
1 dot (most negative camber - shortest arm)
The easy to remember and actual reason for the dots to be this way is that, longer arms give more space for marking the dots!!! :)
For GLA and GLA-V2
 
Model: GLA-023
