Steering wheel vibrating at speed
So I was on the highway the other day and I noticed the steering wheel vibrates around 75-80mph. I took the car to the shop today and they said it was due to my aftermarket wheels not having hub centric rings. My wheels are 18" Enkei LS 5 wheels. I believe they have an offset of 50 (mm?) and a bolt pattern of 5x112. Bore diameter is 72.6mm as well.
Does anybody know the offset of the CLK? I've got an 06 350. I don't really know how to make sense of all the numbers. If anybody could help I'd greatly appreciate it. Also, anybody have an idea of where I could find these hubcentric rings? I've done some cursory googling but I can't seem to find anything other than 73mm to 64mm.
Edit: From what I can tell, the OEM CLK 350 wheel has an offset of 30. Would that mean that I need a 20mm hubcentric ring?

You can try clocking the wheels in the front only, or swapping left/right if they are not uni-directional.
You can also try taking a sanding disc tool and cleaning the rotor mating surface to the wheel and the inside of the wheel mating surface to the disc. Rust can build up and should be removed to make uniform contact. Will it remove your shudder? I dont' know... will it help perhaps.
I've run spacer before and yes they were hubcentric, and I still have the vibes you describe..... I had to clean the mating surfaces, AND find the right combination of clocking the wheels/spacers to get a smooth ride..... I gave up on the spacers after this as I ran out of patience to guess the right rotation.

You seem a bit confused about terms, but I cant tell for sure. Offset does not necessarily have anything to do with being hub centric, but it can. If the offset is far enough off from what it is supposed to be that you need spacers, then you need hub centric spacers. Offset simply measures how far in or out your wheel sits. But if it sits too far in that it hits your brake calipers of struts, then you need spacers to bring them out. Most pacers below 10mm are not hub centric. Hub centric means they have a machined lip the size of the bore in the wheel.

And yes, if your wheels are really 50, and OEM is 30, you need 20mm spacers, which is pretty thick. And longer lug bolts. And the 20 assumes the wheels are same width as OEM - e.g., 8". If you go to 9" for example, you need the offset difference plus half the width difference.

Yeah, I wasn't too sure on what all the terms meant. They are 8" width, and 50mm offset. I'm not too sure about the OEM wheels. I only gathered that they were 30mm from a quick google. But that was from the listing on an Ebay auction. So idk how accurate that is.
I remember it being hell getting these wheels to fit originally. Apparently the shop that installed the wheels wrapped duct tape around the hub to get it to sit flush and not vibrate? That's what I get for taking it there I guess. I recently got into a crash which required the front right suspension to be rebuilt, which is when I found out about the duct tape deal. They removed it, and the vibrating came back. So I guess, despite how ****ing ghetto it was, it worked? I'm hoping the hubcentric rings will fix the issue.
It seems I just need to find out the diameter of the hub itself, but I can't seem to do so anywhere online. Guess I'm gonna have to do it the old fashioned way and jack the car up.

Pretty sure the bore on your car is 66.6 mm. To find what size hub ring you need you just subtract the difference of the measurement of the hub on the wheel from the hub on your car which is 66.6.
Pretty sure the offset on the rear is 35mm.
Are you sure the offset for the aftermarket wheels are 50mm? That number seems a bit high. If they are then you won't need spacers to clear the brakes you just need longer bolts which I'm assuming you already have installed on the car if your driving with them on. Get the hub rings and your vibration will vanish
