Let me know final price also, I might be interested.

put me on the list for one for 03 sl55.
thanks

not to be a party pooper but i don't see $1200 happening. iirc, dealer price is around $1450.

Jangy...we will be wating...

For ME either stock gearing either 3.06 but as far as I know LSD and gears are diff things...

Do you guys think with 700HP + and 3.06 E55 will be undrivable on the street ???

I'm interested too jangy.

Put me on the list too!

I agree w/ SteveBez on this one - 2.82 seems like the way to go if you want to make a change.

Overall may be YES but it doesnt amke mcuh of the difference and hurts 1/4 times cause car shifts to 4th just before finish...

Only if you're trapping faster than 125 mph.

Hold the gear (no shift) and you will see a gain.

If you are only after a couple of tenths, I bet the tranny upgrade can net you that easily. You can measure the shifts with a sundial.

What do you mean HOLD a gear if it needs to shift to go further

I want to trap faster then 125 and Jakpro who has 2.82 gear said it shift jsut before 1/4 finish...

I think Quaife can actually install them for you as well. They sell the product and they also have a couple of techs to install if they are not too far from where you guys live.........

It means don't let it shift. Your car won't stop, trust me.

You probably won't be trapping higher than 125 without nitrous anyway. I don't see the problem.

You also do highway runs where the gearing would help you, IMO.

If you are only concerned with 1/4 mile, save your cash and increase traction. Better tires, a diff, a looser torque converter and a trans that doesn't shift in dog years would be a good start.

I'm very excited because today, while I was at Merc Service for installing my new alcantara F1 wheel I met there a common friend and had the opportunity to convince Merc Service to support me installing (almost) all mods I want.
It' s a long time I would have liked Quaife diff as a first substantial mod.

Point is that Quaife Europe do not officially produce the diff for our 211-219 series ... it seems that the diff that is usually fitted also in US was originally conceived for a truck 215 series.
I attach data sheet for this diff "9V". could anybody check if it is the same we are talking about?


I found an year old long debate in this forum about pros of this diff (I can find links if somebody is interested)
but unfortunately I couldn't find a clear conclusion about best option for FINAL DRIVE: we have 2,65 ratio and could change for shorter 2,82 (used by tuner MKB; in former AMGs, in current SL and in the new 63) or even 3,07 used in CLK DTM.

Jangy,
I also would be interested in this for my CLS55.
I would need a highly recommended installer in the greater NY metro/ tristate vicinity with a reasonable installation cost.
does any one know what such an install does in terms of voiding the factory warranty?
can M-B say the whole powertrain coverage is voided because we put in a non M-B LSD??
thanks for your organizing efforts!

Well Jangy this should be a Hell of a discount!!! Looks like you got the whole MBworld wanting a Quaife. Please bring on the prices, i'd say at least more than 25 People want the LSD....what you got? lol!

no fair teasing bro, post up pictures of that thing how much did it cost also? can you get me one?

So, have people verified real world advantages and gains of the Quaife over the Kleemann diff? Sorry, haven't been on the board in a bit....

Hmmm...How do I make the car not to shift to the next gear ??? Even in manual it shifts...If it woudlnt shift if would hit a rev limiter...

I think with over 700 HP its possible to trap 125 without NOS...

I am not only concerned with 1/4 mile, but most of the races happand on the streets....

I got MT DR for 1/4 runs...

Where can I get looser torgue coverter ...for trans to shift faster I need to get TCU...

I am intrested send ME a link...

The problem is where can I get TCU for 3.07 gear...

From this thread C43's had 3.07 final ratio:
c43 thread

There is some speculation in this thread that 300E's had it too, with 4-speed:
300E thread

Actually, from MB-USA website the SLK32 has 3.07 rear end:
SLK32 link

not compatible.

pronto!

.. do you like?

ps
- official cost available from price list in the AMG web site is about 700euro + taxes, but you can find on ebay at about 450euro delivery included; and sometimes at less ..

Looks good but I like BS wheels better...back to topic guys...

So 3.07 should be OK with 700HP E55

please, what means, in practice, TCU - EGS tune? is it something like an ecutune? .. til now I only understood it is possible to eliminate the torque limiter

in a few mins I'll attach a resume' from former posts about LSD
