[B]Stu: I assume that neither your 400E nor the 450SL had ASR--is that correct?

That is correct.

Also, what year 450SL did you use (or does it make a difference)?

It doesn't matter. They are all 3.06 or 3.07.

Did the housing from the 450SL fit also or did you use another?

No. You have to transfer the parts. I machined the pinion to accept the ABS stator
as the 3.07 never came with ABS and I set it
up in the 124 differential case.

What was the total cost of the job, approx. (parts and labor)?

Hard to say. I own(ed) a Mercedes shop and also owned all of the differential measuring
tools. On those rear ends we have changed the
price usually is around $2,000 gear set included.

How did it affect performance? 0-60?

Prior to changing with the 2.24's my car 0-60
measured 9.3 seconds...In Denver, Colorado.
With the gearing change I measure 7.1 seconds.

top end speed?

It should be the same as the 450SL with 3.07
which is about 136mph.

What if anything did you have to do to the computer chip? Have you done any other mods to it? Thanks for your input.

500e sway bars, 16x8" wheels with 215/55/16's
and teflon/stainless brake lines.
