BRABUS anti-slip differential "LSD"

**alroumi** · 05-16-2007

Guy's since there has been much talk in the previous months about track days and how can I improve my SLK's handeling and so on, Ive just checked Brabus website and they offer their "BRABUS anti-slip differential. 40 per cent locking ratio." for the SLK200K,350 and 55 AMG. I was wondering if anyone had an idea or quote on how much do they go for, due to my local dealer offering their Tuning programs. I was just wanting to know, or compare their list prices to what my dealership will cost.

Thank you in advance.

Great topic Mohammed! I'd like to know all these as well.
In fact I'd also like to hear opinions on any LSD fitted in any SLK.
Has anybody installed an LSD on their SLK?
How does the handling compare to non-LSD (factory) setup?
Do they worth their money, or you don't see much of a difference?
Let's have some feedback!

**alroumi** · 05-16-2007

No problem, Ive been asking the same thing as its a very nice upgrade that can vastly improve the handling of the SLK and accelration times without having it to excessivley smoke its tires, In 55 AMG's case.

and none for a 280!! sigh.
surely 350 one would fit?

Big chance as they are both 6cylinders.

The LSD is vital if you plan on driving the car seriously, not a world of change i don't think but just enough to make it worth the cash.

The price will depend very much on the mood of the dealership as i have said before Brabus don't have price lists for main components you have to grit your teeth and push on with it if you want one just tell yourself the benefit will outweigh the cost.

However unless you track your car or drive it like a rocket in the twisties it's not something worth considering, the difference in acceleration time is practically non existent if you get a proper launch the standard 55 does not need an LSD to get going without smoke it can do that already and if you get a bad launch the LSD will be no help it cant do anything if both wheels are spinning like they would be from a mistake.

Its only needed if you have considerably more horsepower than stock or you push your car to its limits on the track/road and then it becomes invaluable.

Thank you dan, so its not important after all as i dont track my car and we dont have twisties over here.

Would be a waste of your hard earned cash then really mate.

I would suggest maybe some tires with a wider contact patch front and back preferably something that's sticky will wear away faster i know but that little bit of extra grip makes a lot of difference.

I think you will get more results from them during road use than you would from an LSD and they are way cheaper.

**alroumi** · 05-16-2007

I might consider a Evosport U/D pulley as the weather is relatively hot all summer, it could decrease the chance of my SLK losing horsepower from A/C and Electricity ie Radio,CD.

DansSlk · 05-16-2007

Your call mate of course.

Only thing i would add with a modern car the alternators are very stressed components when you consider that the cars are producing more power than an average house needs to keep its appliances alive but its also consuming a huge amount of it with very little current being left for the battery.

After a start of the car from an over-night rest the battery takes approx 30 minutes to return to a nominal voltage, pulley mods reduce the power output further and could cause power issues when high load systems are being used i appreciate your not going to be using the heated seats in Kuwait but things like the AirScarf use huge amounts of power the alternator produces about 25,000 watts and the engine uses 90% of that for itself without the other loads being factored in.

Exhaust headers a good for power especially if you have them wrapped up to keep them hot and lower the bay temp that will increase scavenging and give you a nice kick.

Alroumi,it is not like you do not have a sufficient number of horses ?

LSD's need some experience to get used to since they can be a double edged sword when driving in road conditions. LSD's differ in construction and in the way they transfer the power of the engine to the wheels. In our case I am unsure on how an lsd will interact with the esp system .The esp triggering point may need some manipulating,if you want to use the LSD as it was intended.

DansSlk · 05-16-2007

Its been OK on my car but the ESP is tweaked a mate of mine is getting one fitted to a standard machine so i will let you know how it behaves.

Mine gets confused sometimes but not very often

**alroumi** · 05-16-2007

Any ideas of ways to boost the Hp level abit as headers are way out of my disposable income. Ive got SuperSprint Xpipes, Green filters, Ecu and 200 cell 3" Primary cats. Power delivery feels good especially in the low - mid range tq however I need more TQ at the upper RPM. I think the headers might be the only essential solution towards this. I just hope they were priced more reasonably.

DansSlk · 05-16-2007

As you say mate unfortunately the only sure fire way to get more torque at higher RPM's on a NA engine is headers really

Yes, that is what I suspected. Thanks anyway.

ierax · 05-16-2007

You can always have a look at an s8 kit.think big (or at least dream big

)

Its dream big my friend, I would really like to carv out as much as Ive got from my 55 as a NA.

Ive heared there are schrick cams for our NA engines.

cyberdrakon · 05-16-2007

aren't headers and LSDs going to in about the same price range?

No, I think someone over at mbworld got LSD installed for $1,500, headers are more like ~$3,500, I'm not sure if that price is with or w/o installation.

cyberdrakon · 05-16-2007

Wow, $1500 for brabus LSD is a pretty good price...for my other car, differential prices are over $2800.
