I was having a discussion with my friend, and I'm 99% sure that I'm right. Which groove for the Bilstein perch sets the car at stock height? and which one sets the car 20mm lower than stock? I told him the one on the right (see image above) is the one for stock heght, and the one to the left, is the one to lower the car. He disagrees. Who's right?

Ryan,

You are correct. Put the shock in the position it will be in the car. The one you are calling "right" is the UPPERMOST groove. It keeps the car at stock height. The LOWER groove lowers the car about 3/4 - 7/8 inches. (20mm last I checked!!)

Remember that the spring perches go on like an inverted cup. In your picture you are looking at the BOTTOM of the 4 spring perches, when they are installed in the car. So that side faces down, regardless of which groove you use.

HTH,
