Hi, I've put on h&r+bilstein on my 97 C230k recently.
When I went to do the wheel alignment, the mechanic told me that the front camber is still too much negative, the inner side of the wheel will wear quicker.
Anybody has the same problem? What's the recommend solution?
I am assuming that the rest of your suspension / steering components are in good shape, such as ball joints and LCA bushings.
That said, lowering the car via springs will affect the camber negative. Mercedes never designed the front suspension for camber adjustments and in fact, they came from the factory with a non adjustable or positionable lower control arm pivot bolts.
Later on Mercedes was getting inundated by there techs for some way of adjusting the lower control arm camber. Mercedes followed by creating a new LCA bolt and cam adjuster set. Now mind you this part will only allow about 0.3 - 0.4 change in adjustment depending on how they place the cams on the car.
I know this as I have just completed a complete full front/rear suspension+steering overhaul on my 95 280 and installed a set of H&R springs as well.
Now your car may already have these bolts and cams on the car, as many of these have been retrofitted onto the older C-series already, however MY car still had the originals and were not adjustable, you may want to check it out.
An easy way to check is the new style bolts are silver colored, had a HEX bolt head and the threaded end that is exposed has a C channel cut along the bolt threads to allow self cleaning of threads.
The original bolts were rounded heads with TORX fittings, gold in color.
The new style bolts part # is 202-330-01-18
cost me $25 a bolt kit just last week from MB.
Each bolt comes with 2 cam adjusters
You will need 2 per side on the front LCA's
New style bolt looks like below:
