Hi W208 owners!!! Long time, no see

I have a brand new Quaife QDF7V differential with fluid, bearings, shims, and everything you need to install it. Who wants to make me an offer?

I never had the time to install it and I would like to use the $ somewhere else. I'm including over $250 in parts alone in addition to the differential.

PM me or call my cell 706 878 0525. Pics available upon request (still in original packaging of course). Thanks!

(and please don't rub it in that you get a deal and I lose my diff)

Wondering if there is any benefit or gains for a little ole v6 320. If so what would they be and/or explain what a diff does in laments terms.

VIPclk320

what this does is takes away the clutch mechanisim and brings gears into play which in turn gives you a smoother movement and better traction and better power distribution between the axels. hope that helped. but i know there are more differences but thats as much as i know. sorry couldnt be more helpfull.

Williams707

Will it give me more power? Will it work for a 320? Is this a good mod I should jump on?

da_guitarist

It's a great mod, really. Doesn't bring more power, but improves traction and handling. It sends power to both wheels instead of 1. (2 wheel burnouts and better launching ability). Here's a note from the web:

The Limited Slip differential will send power to both wheels equally when traveling straight, however when one wheel spins due to a lack of traction, the differential will automatically provide torque to the other wheel with traction.

I want it installed, but I need to save up some cash!

BUMP!

First $1k gets everything (free shipping to the lower 48)

Elzin

so on a straight line its awsome, but in corners, the traction control and traction in all will be worse.
also the turn out of corners when giving throttle will let the car slide more easely?
the the thing thats good w this is u get the same torq from both rear wheels when accellerating even if 1 wheel looses its traction?
how mutch did parts + diff cost you when you bourght it?

Which W208 Models will this work for i.e. 320, 430, 55?? The site says this is for a C32

da_guitarist

Will, i'm not an expert, but I believe it works in all the w208 rear ends.

Can an expert chime in?

Also, I do not believe it degrades handling, but it should handle a little differently at the point where traction begins breaking.

they got lots of good info on clk's hope this helps

I'm interested but need to make sure 100% before I buy. Getting tired of my traction control light going off every time I punch the gas even in my brand new Pirelli's Pzero Neroz

dlbehrns

depending on the model i.e. 320,430 or 55 the oem ratio will be different. the question I would ask is, what is the oem final drive ratio on the 320 and what is the ratio on the Quaife which was purchased for a 55? you can bet it will be different but will it work? check this out Wil http://www.quaife.co.uk/catalogue/products/qdf7v

Williams707

Per MarcusF site

http://www.marcusfitzhugh.com/CLK/spec.html

Final drive

CLK 320= 3.07:1
CLK 430= 2.87:1
CLK 55= 2.82

VIPclk320

i personally belive if you use a the quafie thats meant for the 430 or the 55 on the 320 will slow down your acceleration, because the gearing ratio is different on the 320 compare to the v8 55 and 430, i.e. the reason why many transplants such as mine thats going down in spring will be the 55 engine and trans with the 320 diff because the gearing of the 320 will give me better acceleration but in turn i will be scraficing top speed. so someone with more experience should confirm if the 430/55 LSD will slow your acceleration on the 320 or not.

QDF7V Mercedes C32 AMG 00-07MY Quaife ATB Helical LSD differential

Dear Jimmy,

I regret we don't have an application for this car. I cannot be 100% sure, since we don't have complete access to Mercedes EPC datacards for this car. But it seems that you have an early model version, which has driveshafts with CV joints at each end. The later model comes with a one-piece shaft, with no bolted input shaft flange on the final drive. It could be worth you checking, though.

Attached is a pic of the two arrangements.

If you have item 6, then I think we can help further.

dlbehrns

Ash is correct. If you want quicker response you should go to an even higher gear ratio than the oem on your 320. remember the 4.11:1 that came out on the camaros in the 70s? The ratio means that the pinion gear must make 4.11 revolutions to turn the idler gear 1 revolution. They were great in the 1/4 mile but not so great at top speed. You would have even more top end with the Quaife(if it will work)but slower off the line. So if the Quaife is the same ratio as the oem 55 you will be moving in the wrong direction IMHO.

da_guitarist

Really, no other interest?

TTT

320 dreamer

quaiffe lsd has no bearing on the final drive gearing. you reuse your oem ring and pinion gear which determine final ratio. hope that helps you

^
100% correct.

buffyclk500

so it sould fit a 2003 clk500 with a 2.82 rear end

NEMES1S

this thing sell? and is this the quaife that fits SL's?

da_guitarist

Still available. Not sure if it fits the SL or not, but the first $1000 shipped gets it
