Mercedes has this really unusual top-hat design for the rear shock. We must transfer it to our new KW shocks.

We have to remove the top-hat nut. If you try zapping it off, you will find that the top-hat just slaps around in your hand. There is no way you’re holding onto it. Mercedes, naturally, has a custom tool specifically for holding the top hat in place while you remove that nut.

  1. Mercs make for a great drifting car base, they normally have huge caster from the factory, Merc is all about that highway stability.

    But welding the diff on moms car… ouf.

  2. I truly love the idea of an automatic car with a welded diff.

    Even moreso a 204 Mercedes, those are among the last quality cars they made.

  3. I also have a 2012 C 63 bought it as a fun daily to take it to the track here and there when my 240 track car is down. I took the Merc to the track then 1 lap in it goes into limp mode. How are you guys drifting the heck out of the car and it’s not going to limp mode. I feel like that’s more abuse than a regular track day?! Definitely lmk. I’m stumped Because I love the car but I hate that I can’t drive it hard
