Well, received the new parts and the feel sturdy, they were cheap but look good quality. Got them installed along with the lower control arms (used). I havent had the time to take pics, I will post them later. Most of the old arms were "ok", but the ones with the ball joint surely look bad. I'm glad they're gone.

It turned out that the crossmember is damaged too.The guy at the workshop told me that he had a hard time trying to make all the arms fit, since the crossmember was bent too.

Now I'm looking for a crossmember, and I have a question. Will a crossmember from any model/year fit as long as it is R170 platform? I've read the R170 derived from the W202 and seen suspnsion parts from C-Class cars been claimed to fit the SLK320.

I've found these three part numbers that are supposed to fit an SLK320.
