Just Ordered OEM AMG LSD System
I would not be suprised if I see performance numbers being the same or better as modded (ECU/Pulley) cars but still running bone stock
A special thanks goes out to Harris for making this happen for owners in the US!
Have a safe trip back from Germany

Does installation of the LSD void the factory warranty?
Is there a separate AMG warranty?
Shipping weight?
Does it utilize the same gears as the stock diff? If not, what is the gearing
ratio? Are there choices available?
Lead time?
He said he'd ask the same questions of the AMG folks and get back to me.
For those interested in the cost, you need to email Harris @ hartonmotorw01@netnation.com
It ain't cheap, but I'd love to be able to switch off ESP and plant the throttle using LSD. From what I understand, this is the same LSD used in the SL65/CL65's.
Good work. I would consider this for my car. Can you disclose your source?
I love venders who blow hot air about parts that are not sold to the public and how cool they are for getting them. Well look little joe shmoe got the part. And I am glad to see it happen.
Enjoy the diff! As an E55 owner I know it needs it!

??? Care to explain?
if you get some answers from harris, please let me know. i asked him basically the same questions. thats why i did not pull the trigger on this just yet.
cheers,

Spero, can you give me a ring and let me know how much and how to get in touch with Harris? I, too will have the diff shipped to either HBL (not too hot about them right now...although Dave is a good guy) or ASC in Alexandria since I have an awesome relationship with my service writer and the tech.
After diff, I think I'm going to do the EVO or Kleemann headers.
The Best of Mercedes & AMG
MB Service Manager told me since it is a AMG part that he does not consider it aftermarket, therefore warranty not void. Need to remember that this is the same unit that people in Germany have as a option when ordering the car from the dealer.
Is there a separate AMG warranty?
Not Sure
Shipping weight?
Harris informed me that cost to ship to East Coast would be about $110
Does it utilize the same gears as the stock diff? If not, what is the gearing
ratio? Are there choices available? AMG LSD system is ready to be installed. Complete swap out for stock diff. No ECU changes needed.
Lead time?
Takes several months once payment has been made. Looking at a Feb/Mar arrival @ dealership
??? Care to explain?
Harris speaks as if he is the only person under the sun capable of getting these parts and I am simply glad to see that other people are equally as skilled.
False claims bother me and when a vendor say hey im the only person around who has these he best be ready to back it up.
If Harris did infact did get this LSD to the buyer in question then I am wrong but it sure does not sound like it. Im always open to being proven wrong.
Been reading quite a few posts from you lately. Just curious if there is anything you do like. Most of your posts are pretty damn negative man. Nothing personal, just curious if you have anything good to say about Mercedes or any of its products?
Cheers,
Gareth
As for all other questions that you guys have, I will answer them IN DETAIL once I am back from my Essen trip.
Good work. I would consider this for my car. Can you disclose your source?!
I believe that's why Beowulf is lost as well?!

BTW, here's an interesting thread on the AMG LSD: http://www.amg-owners-club.org/board...?threadid=1787
It sounds like everyone on this post has only spoken to Harris regarding the LSD system so I am not sure what others are talking about. I may be the only one so far who has actually ordered and paid for it since I wanted to make sure it is installed in my car by March. My gut tells me that we will not see to many AMG LSD systems in the states so I wanted to act fast.
BTW - For those who have never ordered from Harris, I have ordered things from him and he is very professional and delivers as promised. He is great in responding to emails, so just drop him a line with any questions. He is in Germany as I post this and he has emailed me several times over the past few days.
Alex, I agree that your car with AMG LSD and the Renntech mods that you already have should be scary. We saw you run 12.1 1/4 times without LSD and all that tire spin. You may get into the high 11's once you have the LSD installed

Never had a problem getting quotes from him.
excuse my ignorance, but won't the LSD only help you in the turns and not in the straightaways?
i can see how it would help in the straight parts if you've bumped your horsepower up into stratosphere and you need a way to get all the power on the ground.
but won't the LSD make the E55 better in the turns, which all of us seem to talk about as one of the only downsides of our cars?
also, not sure if Harris told any of you this, but does it come with the software/mechanism to help the installer reprogram the ESP? because if it does not, then it's really no different from what Kleemann or Brabus can offer.
the AMG owners club link is very informative. i just would love to know if this blows my warranty or not. if it does not, it's a no brainer.

Sorry Harris... sell away!
Enjoy the diff
Quick Def on LSD from Kleemann Web-Site
KLEEMANN Limited Slip Differential (LSD)
Better grip - Faster acceleration
Overflow of engine-power is no good if it cannot be transferred into wheel traction. Therefore KLEEMANN has developed a Limited Slip Differential (LSD) with a 60 percent locking mechanism, which means that the mechanical devise applies a 60 percent lock-up ratio between the two drive wheels. In contrast to a standard ESP-system a Limited Slip Differential (LSD) is a very sporty and high-performance approach to control wheel spin thereby improving the cars traction.
At no time will only one wheel receive all the engines´power and by powering both drive wheels at the same time, the engine power is distributed more evenly, hence reducing wheel spin and in the end lowering accelerations times significantly.
Using the KLEEMANN Limited Slip Differential (LSD) gives an imme-
diate result. Testing has shown that a Mercedes-Benz 55 AMG will drop as much as 0.3 second to 100 km/h with this modification alone.
The KLEEMANN Limited Slip Differential is available for all Mercedes-Benz models fitted with a "large housing" differential case. This means all models with V8 or V12-engine.
how does the Kleemann LSD affect the ESP? does it need to be re-programmed or not? does Kleemann offer that if it does?
and does Kleemann offer a warranty on its LSD?
seems AMG's Differential (stock) is 80/20.
AMG LSD Harris is selling is 70/30.
Kleemann is 60/40.
What is the best ratio?
Thanks,
Gareth
I am not a expert, but I assume that AMG is less aggressive for a reason. Both great products, but the AMG system is a complete swap out. Does not
affect ESP and no re-programmng of the ECU.
I went with the OEM AMG system to keep everyhting stock.
I hope this helps. The Kleeman is by far the most cost-efficient solution and has the best division of torque for straightline (computer free) take offs and aids in maintaining lateral balance in the turns as it helps the tires stay planted and therefore offer the most traction they can.
