    New, UPD AMG/Mercedes rear performance suspension kit

    The UPD suspension kits have been in development and testing for over a year now and we have over a 1000 parts in stock for many different AMG`s and non AMG models. We are releasing kits for the AMG and non AMG mercedes W211, W219, R230 and some models of the W212 up to year 2011. Please state year, model and body style when ordering, so correct kit can be shipped. W215, W220 and most all the latest AMG models kits will be released soon, so check back with us, if you are looking for a particular kit.


    More traction, even tire wear, improved handling, better braking and firm muscular road feel are some of the features attained with the new UPD rear suspension kit. Lowered cars and cars with larger tires can quickly adjust suspension back to factory or custom alignments. Wearing out the inside patch of your 300+ dollar tires every 4000 miles can be tuned out with quick on the car tuning.


    With more tire contact on the ground creating better traction, your car will be faster from a dig or a roll. We have seen from a 30-100 mph roll, up to .4 tenths quicker time by improving traction , reducing rolling resistance with better toe angles and less tire wobble.


    The factory camber and toe arms are made with soft rubber bushings that allow a plush mushy luxury ride and compounded by age and use, you get toe and camber wobble.
    Features:

    *Full heavy duty, adjustable race camber and toe arm kit

    * 6061 aircraft grade, 1.25" solid hexagon aluminum

    * Massive 3/4" adjustable chrome molly rod ends

    * Self lubricating, self sealing , injected nylon races

    * Easy to adjust toe and camber settings while on the car

    * Over 26000 lbs radial static load rated rod ends


    * One year warranty

    W211 install

    I'll chime in here since I installed a set on my '06 E55.

    I just came back from the alignment shop. I will say that my car is lowered and the camber wear prior to this was atrocious. I got 7,000 miles out of my last set of rear tires, and Michelin PSS tires are not cheap.

    The alignment shop was able to dial in my suspension to the exact specs I wanted. With the car in Sport 2, I am at a meager -0.5 degrizzle of camber and I have toe at 0. I have only hit it once from a dig so far, but I got much less wheelspin than I would have before. The alignment guys were really impressed with the arms and said I could come back anytime if I needed some adjustments made. They said dialing it in was a piece of cake.

    The pics really don't show how massive these things are. The shipping label on the box said 18 lbs. They are seriously heavy duty. And they look amazing. Too pretty to cover up. Between these and the MBH headers, I have a damn art museum under my car.

    Install "can be done" on jack stands (I did it), but if you value your sanity, definitely get access to a lift. Every problem I encountered was due to the strange German engineering design choices, the worst part, by far, being the bolt location for the upper camber arm. Plus, being suspension pieces, it takes some serious torque to break these bolts loose. It's hard to get leverage when laying on a creeper

    Seeing as how there are only four bolts per side plus two more for the brackets, you need a ridiculous amount of tools. WTF, Germany!? You will need (at a minimum): Torx, E-Torx (inverted Torx), Triple Square (aka spline) bits, Hex wrench, and a variety of box wrenches. Having access to pry bars and stuff like that is helpful.

    Note: suspension pieces may be slightly different between model years. My E55 is an '06 and I think a few of the bolts are different than earlier years.

    Here's a handy pic that shows what tools are needed for the hardware. All the stock bolts and nuts are reused. Good thing MB did a good job making quality pieces. I cleaned all of mine up before reusing them. The Torx/E-Torx bits are T-55 and E-16 & E-18. Triple square bit is an MT-14. This is for the upper part of the camber arm and is not easy to get to. The hex wrench is a 10mm. As for box wrenches, you will need 18, 19, and 21mm. I'd recommend having several sizes +/- these sizes in case your setup is different.

    Note: That little spacer plate on the left, just below the toe arm bracket... I only had one on the passenger side.





    Here's what some of them look like:





    The bolt with the flat head comes from the inboard side of the toe arm. It takes a 19mm wrench to hold it in place. The "thin" nut goes to this bolt and is an 18mm. Unless you have a very thin 19mm wrench, you will not be able to remove this nut/bolt until after you remove the toe arm from the bracket. Breaking this one loose with the arm already off the car was pretty frustrating. The bolt head is really thin and the wrench loves to slip right off.

    The new toe arm brackets will use these two bolts. They go into two holes on the frame, but getting them in there is... unusual. The threads inside the frame are in this weird little bracket. The washers for the bolts are weird. You need to make sure that all washers and spacers are reused, maybe consider adding a couple of washers to both of the bolts. The reason being that it is easy to run out of threads before everything is nice and tight since the entire bolt is not threaded.




    I recommend leaving one side intact until the other side is complete. This will let you use it as a reference in case you need to see how something goes on again.

    Also, my exhaust setup had the pipes going from resonator to the mufflers right in the way of the bolts to undo the toe arm brackets. I was able to flex the exhaust downward and then jam a piece of 2x4 in there somewhere to give me the clearance needed.

    Take your time as you go and it isn't too bad. The worst part, by far, is the upper camber arm bolt. It has a really fat collar on it and to remove it, you need to take the nut off, which is difficult. It is too close to the frame to get a socket around it, so air tools won't work. You can't even get a ratcheting wrench around it. Doing it from the side is not possible unless you remove the sway bar. Getting at it from underneath is the way to do it. It's a 21mm. I used a 24mm wrench as my extension to get some torque on it. You can only get a little bit of a turn on it, so it take a long time. To make matters worse, the head of the bolt (uses the triple square bit) is way up there between the top of the airbag assembly and the frame. You need to hold the bolt to get the nut off. Use the breaker bar to go up from the bottom and try your best to get the bit in there. This part is really hard if you have big titty-squeezers (hands, duh) like me. You can try to reach around the airbag to get the bit in there. Once the nut is off, use a long screwdriver or prybar to push the bolt out. Odds are that the collar will hit the airbag assembly. Don't be a pu55y and hit it with some force to get it out of there. To get it back in, I put some masking tape on the bit and jammed it into the head of the bolt. Putting the bit on a short extension let me insert it from behind the airbag. Again, huge pain in ass and balls.

    Hope that helps someone. Ask more questions and I or someone else will try to answer.

    Wink Cost of this obvious Necessity!

    PM me the cost for this for my 2004 CL 55. I'm doing the front end next week, why not the rear. It's only money and college is too much of a liberal indoctrination. Better that they learn real data.

    If I'm going fast enough, it is damn hard for other cars to hit me, I'm a moving target. The first rule of safety!!

    I need this for my '05 E55 Wagon. Would probably work for my '08 E550 - it eats rear tires too.
    W211 ('05 E55 Kombi, '08 E550), R107 ('78 450SL 5.1), R113 ('66 230SL 5-speed)
