R170 - SLK32AMG Steering Wheel
1) remove the airbag (2 torx on the back of the steering wheel)
2) disconnect airbag connector
3) disconnect 2 horn leads
4) remove 10mm hex allen bolt holding wheel on
5) pull to remove old steering wheel
reverse the process for putting the R170 wheel on...
Everything fit, SRS (airbag) connector, horn leads, even the contact ring openings on the wheel itself were the same.
15 minute job.
The wheel cost me $300.00 from ebay....

The 2000+ wheels/airbags do fit the W124 though, but the airbag is not compatible with the W124 SRS system and it won't deploy in the event of an accident.
I don't have an answer on the Smart car, never heard or seen one installed on a W124. Not even sure if the splines on the wheel would be compatible, let alone the airbag. My guess would be no, but if you get a chance to pick up one of the wheels go for it and report back.

What do you think of this wheel for the money?

I'm quite in love with the moulded handles and the look. I believe they are built off of OEM Mercedes Wheel cores.

Looks like you have a 1990 model, to use this wheel, you will need a 92-93 contact ring to go with this wheel.
Also, be carefull if you decide to buy one of these "custom built" wheels. Make sure you get the internals and you know what year the core is from. 92-97 wheels use the same airbags, but 98-99 wheels use a different airbag. Although the wheels/airbags all look the same, they are not interchangable (can't use a 92 airbag on a 98 wheel)

Even though redlinessport lists themselves as being in Rowland Heights, California, the wheel shipped directly (but quickly) from Taiwan and the Paypal invoice showed the company was in London - worked for me, but could be an issue if you have problems. I have attached a pic of my wheel which I think is higher resolution than their ebay pics.

Pretty sure that wheel is 400mm, the Sportline wheel was 390mm. 92-93 wheels had the contact ring on the back, 94+ has a black plastic filler piece on the rear of the wheel. If yours has the plastic filler piece, you would need to remove it and install the contact ring. If you indeed purchase a contact ring, make sure you get the screws for it as well.

I need the newer style ring than the one on my current 90 wheel right? However, would the screws between the old style ring and the new style ring still be compatible?

Don't know if your screws from your 90 will work or not, never tried it.

This wheel appears to still have the contact ring. You could always purchase this wheel (or one like it), take the contact ring and then re-sell the wheel.




BTW, I sent an ebay "ask seller" question and asked them to confirm fit for the W124. They did and it did.

Sorry if I'm threadjacking/being a pain in the *** tmaguire, just collecting information as always :\
We're a bit closer to finding out about the Smart Car wheel. Tbone has told me that the stock American Smart Car airbag is 2-stage (not compatible?), BUT the Brabus one is 1-stage (possibly compatible?).
There are also some pictures of the Smart Car wheel in that thread but we have no sizing reference.
