Hi to you all out there.

Is there a smaller diameter steering wheel available anywhere for the R170 SLK ?

This could even be an aftermarket offering but compliant with the airbag requirements.

One question? Why are you asking? If there is your current AB will not likely fit and from there it gets messy.

I do believe that AMG's are smaller by ½" - could work out to be very expensive.
R170 SLK AMG, W208 CLK AMG, W210 E55 AMG etc. - good luck in finding one :surprise:


I did find this whilst poking about :)

Steering wheel standard sizes:

A – 15 ½” x 3”
AX – 15” x 3 ½”
AXX – 15” x 3 ¾”
B – 16 ¾” x 3
BX – 16 ½” x 3 ½”
C - 15” x 4”

Hi @ARoosterinaRoadster ,

Momo (and maybe Sparco ?), do Airbag Wheels with a good selection of Bosses, used them a lot in the past ;)

I used R171 Wheel on mine, and wired the Buttons to control Android H/U and Paddles to shift the Trans, lotta electrical and electronics work involved though :grin:

HTH, Cheers Dave

Hi Alex. The steering wheel on the SLK is slightly large in diameter and is in direct view of the view through the windscreen,the fact that there is no rake adjustment is annoying.
Other premium brands had long included Rake and Reach adjustment;the wheel gives the impression of late 1960's small commercial vehicle but without the hard plastic feel !!

Hi Marcus. Thank you for the details but I was hoping for something relatively straight forward.

Hi Dave. Thank you I will look into the Momo and Sparco but playing with electrical connections is alien territory for me !!

Two comments. My wheel is a combo of wood grain - albeit plastic - and leather.
Second, page 64 of the owner's manual speaks to the telescopic feature of the steering column.
Do you perhaps have your seat set too low so the wheel is in your line of sight?

Mr Rooster has mentioned before that he is of very short stature ..

I reviewed all the posts so I must need more coffee because I can't find that comment but it does support my thought that maybe he has the seat set too close to the floor. If he is short then telescoping the wheel tight to the dash tends to lower the height of the centre point of the wheel and if he lifts the seat he should be able to see over it. If his "short stature" is in his legs (my Mom always complained they built the sidewalks too close to her butt at 5 ft 2in) moving the seat forward will also lift it a bit. Of course he does not want to be too close or he will lose proper arm position. There is always the idea of a cushion.

Hi Alex. No,I have the seat at the highest position (front & rear) and the wheel at the furthest in and drive in the almost arms out mode when in the ten to two on the wheel.

I have the other day just lifted the rear of the seat rails and inserted 20mm spacers because I felt that I was sitting in a hollow;and no the seat is not clapped-out,indeed it is rather supportive albeit now at 62,000 miles.

Ah ha. Someone that really does read mark and inwardly digest !!
This was mention in a previous semi related topic by me,as I recall with regard to the R171 and the improved driving position even with the manual seat adjustment,rake and reach without the electrics.

I am 4'10" tall with a 23" inside leg measurement and slightly short arms (arm-pit to index finger/thumb intersection 22".
My torso length is what it would be if I was 7"/8" taller.

I drive with the backrest reclined away from the steering wheel;I also have the accelerator pedal built up so as to make my right foot more comfortable when driving.

I have a pal in Shropshire that is circa 6'7" and if he kneels down we are level at the eyes and if we sit on a flat surface we are level at the tops of our heads.

Further to my previous reply :--

Who would ever guess that the driver of this SLK 230 Automatic was 4'102 tall ?

The real clue is in the accelerator pedal being built-up.

Full mark for trying mate. Here is a perhaps wild idea.
These cars use a lot of parts from the W202 C class which is why we only have the telescoping wheel.
The W202 was replaced by the W203 which has a tilt and telescoping wheel. I found myself wondering how bit a deal that might be to swap it so you get both functions if it is even possible. Even if you could adapt the top parts of a W203 column to the rest of the existing might be interesting because these steering columns are built up from pieces, Dave could tell us I am sure

Hi,

I'm sure it can be done, but it won't be easy ...............

The biggest likely issue will be that all the R170 Stalks do not direct fit the W203 Column and Vice Versa .................

The R170 Stalks are all old skool hard wired, where a lot of W203 functions are all CAN Bus Controlled, the R170 does not have a suitable CAN Bus for all that :wink:

This is why I had so much Electronics and Wiring malarkymabob to get the R171 (also used on some W203's) Steering Wheel Buttons and Paddle Shifts working >:D

Also the later 203's had Electronic Steering Lock, that could be an interchangeability issue too ;)

Later down the line I might buy some EBay bit's and look at this as a cool mod for my own Car but as said, it'll not be easy ;)

HTH, Cheers Dave

Hi again to all that have contributed with responses of all types !!

I have come to the conclusion that it must be an optical illusion that gives the impression that the SLK 230 steering wheel is so large in the cabin.

The wheel in my BMW 330i Touring is actually a mere 7mm smaller in diameter albeit the steering column is set at the lowest rake position and the furthest inward reach position.

The SLK is set at the furthest inward reach position but is of course devoid of rake adjustment.

My driving position in both cars is as near as one can get to being the same.

Thank you one and all for your contributions.

@ARoosterinaRoadster

If it's a question of not quite being able to see over the top of the wheel .. I've seen loads of flat bottomed wheels in my time, why not get yours reprofiled and give it a flat top from 1030 to 0130 or something like that?

Someone like Royal Steering Wheels could do that for you ;)
A selection of wheels from our sponsor Carid shows that ONLY the bottoms are flat, never the top. There must be a reason for that.
