What rear diff does a 2001 CLK55 AMG have?
Has anyone done a gear swap?
I know we're running the same wheel sizes. The Dunlop Direzza Z2's solved my traction issues for a street car. They rubbed in the front from their wider tread footprint. I'm switching the front tires to same size narrower footprint Sumitomo HTRZ III.
This is for a spirited daily driver not race application right?
I'm interested in updates if you switch out your diff and what your results are like.

This PDF might become some use for those working differentials. no AMG but all the possibilities.
I have a 185/ 3:27 non LSD/Qualif lying about for grabs.
Beefstall is right about the tires, I had fresh Yokos on the front and installed Nittos on the rear. After Autocrossing several events The Yokos are blistered while the Nittos are ready for more.

The 3:27 was not real streetable with a 722.5 4 speed but this TD would leave any 6 and some older v8 in the dark.
You should not have to tune for Gear ratio in most cases ECU.
I have never opened up our 5 speed but if there is a mechanical governor (as in most at) the TCU should recalibrate on its own after a reset during a gear change.
There is one post I know of that a wiseman from Texas installed the 5 speed behind the Diesel 3:27 diff. with a custom built programmer.
TCU/ECU Needs conformation/ VSS Vehicle speed sensor will be off/ Calibration reccomended
