The Best of Mercedes & AMG




I just took off all spacers yesterday to move my daughter to university today. I didn’t want to risk rubbing tires as I stuffed her whole life into the car.
It’s so silky smooth now that I have to retract what I stated before! I do have a slight vibration with the front ECS 12.5mm and just didn’t pick up on it. Removing spacers the car is on rails.
I wonder if it crept in over time slowly? I feel I would’ve noticed if it was like this when I first swapped spacers in.
My theory is the rears vibrate too! But there’s airbags buffering it and and no steering wheel to feel it through.
I’m opting out of spacers for now.

Ugh
B. I could see shaving off/machining the back of a wheel to add "positive offset". How would they add material to give a wheel "negative offset" (Make it stick out more twd fender side). I have heard of shops doing this sorta thing to steel wheels. They literally cut off the face/disc/spokes, cut the barrel and add a strip of metal to widen it and weld the face back on. Sketch much?! I would be very interested in hearing how they could do that to a nice forged one piece wheel (not t hat I'd trust it).
C. After all it's said and done, wouldn't it better/safer/somewhat more cost effective to simply get a new/different set of wheels?

This chamfer is too large and the smaller wheel bore interferes with this larger diameter and can’t let the mounting face truly touch flat. It’s close, but no cigar. Notice how it’s galled and worn after a few weeks... no good. I was wrong in my posts up there where the spacer seemed to sit flush in the wheel. From the wear my spacer is showing apparently it doesn’t.
Im really interested now if the 15mm ECS or HR or ? will have this chamfer or not.
Do I clearance my wheels? I’ll look harder soon…

I’m going to paint my wheel mounting face with machinists blue and gently rub the spacer on it and see exactly where the interference is.
And, I’m going to more carefully inspect the inside bore of the spacer and. make sure it’s not doing the same thing mating to the hub. If it is I’m not even going to try the next step of carefully clearancing the wheel chamfer to clear the spacer chamfer only after sitting on the garage floor contemplating life.
I’m also ordering HR 15mm to see if they’re different. Yes it’ll rub more but now I have to know! I found this older thread:
