We have alot of talk about front camber bolt kits on the forum, but I have yet to see a brief write-up on the install (or perhaps I over looked it).
I wanted to make sure the Mercedes dealer didn't shaft me (pun poorly, but forcefully intended) again with the incorrect parts. I ordered 4 bolt kits for my 320 (2 are needed for each front wheel); yet looking at the wheel/suspension setup I can't tell for the life of me where these bolts get installed. The rear camber arms were a straight forward install, but these size bolts just don't appear to match up to any other parts near my front wheels, and especially where I would assume the camber gets adjusted by the..drumroll please....front camber arms.
These bolts replace the two inner front control arm. It hold the control arm to the chassis of the car. The trick is to install one bolt at a time. Warning, after install the bolts, your ABS/ESP system could go crazy that might require you to get the alignment ASAP.
Those are the correct parts. Like Linh stated they replace the bolts on the control arm where it bolts to the body. If you take the nut off of the stock one you will see a circle with two tabs on each side. the grove in the bolt allows the adjustment while the washer fills in the space.

I just paid for an alignment after installing new wheels and rear camber arms. Does this mean that even if I install the front camber bolts for a "perfect" fit that I am going to need a whole new alignment?
The front wheels only have a very small bit of negative camber, so I don't think there is going to be a huge change once the new bolts are in.

You will only need to align front end.
Those rear of front arm bolts do caster as well
BUT if you change camber toe will need redoing after.
Do 1 bolt at a time
Support the control arm with a jack so it will not drop down
Remove the old bolt
Insert the new bolt with a washer on each side
The raised "V" on the washer fits in the teeth on the frame at the side of the hole
The pictures are of the left side
I have noticed that all of the bolts under the car are installed bolt head to the front and the nut goes to the rear
I attempted this job (with the appropriate location of the bolts noted this time) and had a heck of a time lining up the first bolt after removal of the original. I had been using a jack to support the control arm but after messing around with it for fit, found myself all out of wack. I used a tie down strap to help me pull the control arm back in place and ended up putting the original bolt back in place after having such a time of it.
What I can't figure out is how these bolts adjust camber, since the bolt hole appears to be only so large with hardly any room for adjustment using a new bolt. I realize the new washer with the teeth "pull" the bottom of the wheel/camber back in to adjust for the negative, but it just seems to be such a small amount. Is it really going to help?
I was going to get a refund on the bolts and just live with the front wheels having some - camber, but if this 3mm actually is going to correct something worthwhile, then I will attempt the job again. What is the actual degree of camber correction that these things provide? (If I have say -1.5 camber what will the end readings be with the camber kit?)
