SL55/63/65/R230 AMG: Quaife LSD differential installed on SL55


I need a Quaife for my W203 non-amg rear diff. Can you tell me if Autotech/Quaife has an appropriate ATB diff for my W203? They have 2 versions, 210 axle and 215 axle. I think my car might use the 210 axle version. Any helpful advice would be appreciated. Also, did you install a Quaife on the K32 sedan?
Thanks,

I've been doing a search LSDs, and all I can find are teh Quaife and Kleemann. Is there really a major difference between the Quaife and Kleemann?
Can anybody provide any input?
Thanks in advance.

I'm trying to mod my CLK55, but there just aren't any direct roadmaps...
All I know is that the Kleemann is an LSD and basically has a locking mechanism for the spider gears. I think similar to the good 'ol Phantom Grip from my ricer days:

The problem with these were that if you didn't put them in right- it could be a very costly mistake.
The Quaife is an ATB, which is a torque biasing limted slip diff. (although they sometimes don't call it an LSD)

I guess it's more like a Torsen diff (AWD cars use Haldex). These are geared torque sensitive diffs rather than clutch-type torque sensitive diffs and speed sensitive diffs like viscous-coupling LSDs.

Hope this helps. Please let me know if you get a straight answer about the Kleemann versus Quaife.
I ain't putting one of these into my ride until someone stands up and says- "I've got XYZ and it's allowed for me to drive my car like I stole it and everything still works."
I put a Quaife LSD in my modified SL55. I had reprogram, pulleys, headers, free flow cats, etc.. done at the same time.
The MB installer said I was wasting my money on the LSD. After I had everything installed, he said it was the nicest improvement on the car.




LSD makes a big difference while driving very fast, you can control the rear end in a much amuzing and safe maner. And for power slides it´s just amazing, you literely have the rear end slide controled with your right foot, car has much more linear behavier. I drove several Porsche with and without LSD and while turning on 45ª curves the car without the LSD would loose part of power on the inside rear wheel, while the car with LSD would transfer the power for the outside rear wheel, giving you more power and speed while turning.

I was in ATL a few weeks back and tried to call you with no luck. I can install Quaife units in Houston and Detroit. I would have to recommend shops in other cities.
Makes the cars so much easier and more enjoyable to drive.
In my book it is the first mod for any AMG car.
.......As far as Quaife vs Kleemann, I understand the technical differences. I am wondering if you or anyone will comment on on-the ground differences while driving. I personally have not found the Kleemann LSD, which I currently have to be that much better than stock in controlling wheel spin on my s/ced W210 E55. However I 'm no expert.

Quaife vs 030? I have not purchased yet and so I am looking at an 030. I can get a nicer, lower mileage non-030 but really don't like performance cars without LSD.
And, what's a reasonable labor charge for this?
Thanks
