C55
I got the diff back today and was told that, as well as the backlash, the side bearing preload was also excessive. The fix was simple; one of the circlips (presumably the one on the right side) was machined down. This had the effect of reducing both the preload and backlash.
There was no need to add new bearings.
I was told that the diff now is smooth, has good preload, good backlash and a good pattern.
The backlash is now .13mm, which is right in the middle of the limits
I plan to start fitting the diff back in the C55 tomorrow.

C55
I have been driving the C55 with the Wavetrac for two days now.
Under normal light driving conditions, there is no differance to the driving characteristics.
However, when driving more spiritedly, the exits from corners are noticeably better. The C55 now launches out of corners and activating ESP (traction control) is a thing of the past.
This is the result I was looking for.

Hi Morphh
My understanding is that the C55s runs a beefed up HAG 215 diff; the same size as the AMG 63s.
The C320s have a HAG 198 and the C32s a HAG 210.
So, while the diff housings may be interchangeable (?), the C55s use a much stronger unit.
The problem I have with using a lower diff ratio; is the extremely low overdrive of .83.
In its stock form, the C55 revs at 2300 per minuite at 110 klm/hour (68 mph), which is fairly hight for a V8.
Lowering the diff ratio would only make highway cruising worse.

C55 and c32 use the same final drive
C32 and c55 use same 3.06 rear end c320 3.07 w210 e55 and most v8 Mercedes before c55 use 2.82, that's why c55 feels more spirited than the w210 e55. W140 w211 use 282. Blew the diff in the c32 and did lots of research. Ended up using a c55 rear end in the c32 and both wiestec and quaf had the lad available. So I don't see why you don't just order a c32 one and ride
