I'm guessing it's the tires.

Lincoln, very good suggestion. They did do that and the wobble was gone. So it is either the tires or the spacers used to fit the Brabus. I am not sure if the wheels fit without spacers. Anyone know that? If they can be placed without spacers, I may try that. So I've narrowed it down to wheels, spacers or tires in growing culpability order. Any thoughts re: spacers?

I can live with it. But it didnt do it with the 18`s. The 19`s are a bit heavier
but from what I am reading here we are having the same issue.
I pounded mine the other night. ESP Off. Here are the results. And I was not pointed straight when I hooked it up either. Just dont over correct
when it does it and you should be fine.

We can double check if you know the offset for the wheels. Standard SL offset is in the low 30s, e.g. my AMG Style 5s are 18x8.5 ET30 and 18x9.5 ET33.

One more thing to check is the lugs. Since you are using spacers you should have longer lugs then OEM. Be very sure that you lugs are long enough to get at least 5 thread into the hubwhen tight. This is probably not the cause of the slipping feeling but it's a huge safety issue if you are running lugs that are too short.

The offset is often stamped on the inside of the wheel, usually on one of the spokes. If the offset isn't stamped on your wheels you can try contacting the manufacturer or dealer and asking for the info. A good wheel shop should also be able to measure it for you. It's a little tricky to measure yourself it within 1mm of precision.

sound 8 SL55 wheels
Sorry to change the subject a little, but I think my 18 inch wheels are to
small , I am also thinking of lowering it. I like 19 inch, I like the 65 AMG wheels
but too much money, any one seen or fitted Carlsson multi spoke.
Any suggestions would be apreciated, inc lowering.

It's 100% Michelin PS2's
I just did the same swap to aftermarket 19" & 295's directly after install I got the wobble/wiggle upon heavy acceleration, it's documented over in the W211 E55 forum they had the exact same probs when using Mich PS2 295's..
The cause seems to be the extra SOFT SIDE-WALL ON THE PS2's it causes the wiggle, I'm just beating the sheet outta my PS2's & switching to another brand w/stiffer sidewall...
It's not your spacers

Hey Thericker
I got my Intercooler pump fixed and been pounding mine a little.
I totally agree its the tires. The Tire wall construction makes sense
as the flex point. They are good tires but this is "an issue".
Next time I may go to the OEM Bridgestones or ???

If you simply touch the sidewall on the PS2's before install you can feel how soft they are compared to others, this is a good thing for Dragracing but for some reason the 295'-up sizing creates this crummy wiggle...
Another good brand is Pirelli

I was wondering if the Michelins that you used had the "MO" designation?
I had an exchange of e-mails with AMG in Affalterbach about changing the rims on my CL55 from 18" to 19" diameter. They suggested part numbers for the correct AMG rims to use and emphatically stated that I must use "MO" tires for safety reasons. The term was new to me, so I e-mailed back for clarification their response was "MO" = "Mercedes Only".
Ultimately, I did not change my rims, but I do remember seeing some Michelins in the U.S. catalog as being designated as "Mercedes". Maybe they have a higher load rating or an ability to withstand higher heat?

Yes I spoke with the Michelin engineer about "MO" and he said it is Mercedes only and they are usually small changes made to the tire requested by Mercedes. My Pirellis have the same "MO" on the sidewall.

I almost crashed my car last night when racing a BMW because of these rediculously BAD tires. My car swayed sidw to side and almost hit the BMW and I felt completely out of control. This is very bad. I am going to complain to the dealer I bought the car from.

I have PS2's as well and am getting the exact same driving on water feel, I filled them to 50PSI and it's a bit better. Can't wait to be done with this set...

Dealer is giving me NEW AMG wheels and exchanging my tires for me. I told them it was the closest I've come to crashing in a long time. The car is UNSAFE with Michelin PS2's, PERIOD! There should be some action taken against them to change their manufacturing. It is dangerous.

Did your tires have that designation, or were they the normal Michelins?
When I was corresponding with Mercedes-AMG in Affalterbach about using 19" rims, in place of my stock 18" rims, they made it very clear that I must only use tires with the "MO" designation.

got my toe links from renn tech. i put them on and the car was dangerous until i had a four wheel alignment and the toe links properly set up. the car handles noticibly better and does not act like it is on water with ps2's.

Can you find a person with stock wheels and tires to try, perhaps a Merc dealer, it would tell you straight away. My thoughts are that the tires you have are wider perhaps with more offset than standard which under power
are going from one outer edge to the other, a bit like torque steer on
front wheel drive. This thread has put me off buying some 19 inch Carlsson
wheels for mine. The trouble is as soon as you modify a car problems start,
maybe it's better to leave them standard/stock.

Problem solved!!!
The Mercedes dealer; Bernie at Escondido Mercedes was a true gentleman, stepped up to the plate and GAVE me a set of AMG monoblock (new style) with Bridgestones to solve the problem. I gave him back the Michelins. I also think that in addition to the lack of MO rating; the 295's ballooned too much since they were maybe too big. Maybe also spacers. Very happy. Problem solved. moving on to other things.....
Thanks for all your help.
