I have been planing to upgrade to KW V3's on my EVO MR and have learned that the KW V3's on the CLK63BS are a hybrid of the V3's. Here's a conversation and what I was told by a person that would know about these things.

So, the stock KW V3's on my Mercedes CLK63 Black Series are chopped liver?

"No as a matter of fact the dampers I am recommending were developed with the "Blacks". They use the SS casing due only to the fact they need to live for 100K Km in the "real world and they want the corrosion resistance. They have the oversized rebound control and the updated and larger compression valve too."

It's never too late to learn something about these F1 safety cars...

Yeah, MB didn't scrimp on the suspension of this car. They could have made the rear alignment parts a bit more adjustable ... but they may have a reason for not giving us more latitude.

I tightened my KW's down for a track day and now they're squeaking like crazy.

They SHOULD have made the camber adjustments separate than ride height like any P or F car-

I'm not clear on that, the ride height is controlled on the strut tower and isn't camber set by a control arm?

Tower???? Ride height is set by the threaded collar. There is no camber adjustment on the control arm just toe.

Strut tower, you know the thing sticking straight up into the engine bay? Okay, call it the strut for clarity.
The threaded collar is on the strut itself, we agree this controls height.
Without looking at a drawing or being under the car, I contend there is a control arm for camber.
I've had mine out to -2.5 degrees and I don't think adjusting toe will get it that far out.

Camber is adjusted with either camber plates, which by the way are located on the strut tower , or with the lower control arms. If you lower the ride height, it will automatically give you more negative camber. And last but not least, toe is adjusted with the steering tie rod ends.

Cool I didn't know it had that adjustability. I thought it was the same poor setup as the other w203 chassis clk.
