Hello friends,

I was considering purchasing a Wavetrac LSD, but I have some questions:

Is an LSD important for an SL55?
What differences will it make?
And is it worth 1095$?

Have a good weekend,
Jad

Good question and one I would like your feedback on guys.

I know for the SL65s they help out a lot but IDK about the 55s

How come mb didn't have them as standard?

Because if your not north of 500hp you don't need it.

MB has it standard for SL65 but its an electronic LSD not mechanical, SL55 I think you had to get the P030 package with the 65 brake kit and 65 LSD

It is too bad the SL55 doesn't have an LSD while BMW M3 (which was only 343 HP, comes with an LSD). I just would like to know if it really improves the car, or its not that important

By installing an LSD Differential you would then be able to deactivate the ESP (Electronic Stability Program) and keep the engine revving wide open to spin both rear wheels equally.


On my W220 you can feel the engine management computer retard the RPM's when the wheels lose traction and start to spin. I don't know if there is a different programming system on the more powerful SL versions but I have seen Youtube videos of those models with smoke bellowing out of both rear wheel wells on drag runs,

I wish I can buy the Wavetrac LSD for $1095 for my car (W220 S65)! Worth every penny!

If your car can smoke the tires from dead stop without power braking, the LSD can be very benefitial as your electronic LSD won't try to jam the brakes on the wheel that may have less traction than the other wheel which I think is totally counter productive especially at the track.

I would rather have my mechanical LSD deliver power to both wheels without the computer interfering with my forward motion by engaging the brakes due to unequal wheelspin speed between both rear wheels and not to mention that my right rear wheel brake pads are worn down way more than my left wheel due to it being the "default" wheel that loves to break loose first under hard acceleration!

I also have an '08 Toyota Tundra with 5.7L that the factory claims it comes with "Rear Locking Differential" as standard equipment. I was VERY disappointed to find out their "Rear Locking Differential" is nothing more than an electronic LSD which utilizes the rear brakes to slow down the spinning wheel which again is VERY counter productive! Thank god the aftermarket mechanical LSD for my truck is only about $600 to buy.

There's a Quaife LSD for SL/S/CL 65 the SL65 is about 1300 but the S&CL is about 2 grand, idk if there's Wavetrac LSDs for the 65s
