Pics of 4matics on H&R super sports
I was hoping to see some images of AWD w204s lowered on H&R Super Sport springs. I understand there is an existing lowering spring pic thread, but there are only a couple that make mention of the vehicle being a 4matic. So if your car is AWD and lowered on Super Sports post it up!

Damn, that sucks. I was just about to order a set of these and came across members saying they bang a lot and are noisy up front. I can't believe that no aftermarket company has put out decent suspension for the 4matic w204, almost makes we wish I went with an RWD model.

Based on another guy that used H&R SS's on a 4MATIC, he said there was lots of banging in the front. No engineer at H&R said you should do this, and this is why.
MB had to move front suspension stuff around to fit half-shafts to make awd. In the process, they effectively moved the spring location more toward the for-aft centerline of the car. This change the Motion Ratio ( spring deflection vs wheel deflection, and that ratio is squared to see how wheel rate changes with changes in spring position (MR).
Bottom line, the front H&R SS Spring for the rwd, when placed in the 4MATIC's front, does NOT provide enough spring rate (due to MR change). With 4MATIC on ground and SS's installed, the front springs will have compressed beyond the normal range, and are in the stiff range with all the closely spaced coils collapsed. When the front end sees and bump on the road, the compression travel is limitied and quickly collapses tha whole spring, with a bang !
If alot of people ask H&R to make just a front SS coil for the 4MATIC, ( the rear SS springs from the rwd do work properly on the 4MATIC ), thay may respond.
For shocks Bilsteing B6 are available (special order) for the 4Matic.

Well maybe i'm the exception to the rule, but I have a 2012 c300 4Matic on H&R SS and it doesn't bang at all when I hit pot holes. But I have to admit that I am also paying attention when I drive to pot holes since I live in the capital of pot holes.
I have 18" for my winter setup and 19" for summer. No banging at all with both. Oh, and I have the 5mm pads in the back.
So don't generalize - maybe it's just an installation issue with the H&R SS....

My point was not to generalize about the knocking up front. I am generalizing that all aftermarket spring suppliers that sell lowering springs for the rwd W204 also state that they are not for the 4MATIC. If they do supply them for the 4MATIC, the set has a different part number. In fact, only H&R sports have a part number for 4MATICS.
It is not an installation problem. It is a design problem, where one of the many design factors is violated if the SS are used on a 4MATIC. You will not know right away if the springs are overstressed and will fail after a finite number of cycles, vs the usuall design basis of near infinite fatigue life. They could also be rding on the "stiff" state of the spring, vs the soft rate.
I recall a thread where 6 out of 7 users of SS springs on RWD were not happy with the ride. Read 1st 3 pages, emphasis on 2nd page.
Harsh ride on H&R SS
A lot of the problem is people not putting Bilstein B8's (or mabe cheaper B6's) on their RWD W204's, to match the stiff range of the spring.

You noted that you were careful around potholes. Your degree of concern when driving may make you the exception to the rule about knocking. Blazitup may be the more typical result with knocking up front.

this is true, may i not hear knocking cause i am very cautious and long island roads are terrible might i add. the ride is very bumpy at times. due to this reason i am saving up for V3s. id prefer the stiffer ride over the bumpiness.

Stance has it's issues regarding trying to use it as a DD. On my other Mazda6, I switched from 17" to 16" wheels so the tire sidewall can compress if I hit a hidden pothole, and added a rear sway bar to eliminate the FWD understeer. I smile as I fly through twisy bumpy roads without a squeek.

Once again, you definitely cant's use V3's unless they specifically list a separate part number for 4Matics. The bottom of the front shock housing is completely different in how it bolts to the spindle.
