aiming

I'm sorry if this topic has been covered elsewhere and I am just not finding it. I need to adjust the aim on my bi-xenon headlights on my U.S. spec C55 AMG. Anybody else had to do this? Thanks for your replies.

Today driving back I hit a real nasty pot hole. I noticed there after the beam of my headlights was odd. On dipped beam long range (range) of the beam had decreased and the lights were aimed at the ground. On full beam normal (for full beam) illumination seemed as normal, but the dipped beam...

Saw this on clubw202.com, think it looks gorgous. Are those 18" AMG monoblocks and C43 kit? How much has it been lowered, cos its sitting perfectly IMO. Thanks
