Installing KW Clubsport Coilovers on my moms C63 AMG
C63 AMG KW rear suspension
Now we can install the spring (the adjustable spring perch should be at the top if you choose to use it). We can also now place the shock in position. It really helps to have a friend push the shock up into the strut tower while you thread the nuts on in the trunk.

We torque down the top nuts of the shock.

Next, we put our jack back under the LCA. We compress the spring until the holes for the bottom shock bolt line up and torque down the bottom of the shock.

With the shock torqued down, we line up the knuckle to LCA holes and torque it down as well.

Of course, just like with the front, wait to reattach the sway bar end-link until you finish the other side!


  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
