Offset....What are you running???
I'm looking to get some new wheels, but i want to know what the lowest offset I can run without the wheels sticking out past the fenders.
If you have wheels, I appreciate it if you can post your size & offset and maybe a picture?
Hopefully this thread will help others who are looking for wheels
Stock 17in wheels (correct me if i'm wrong)
-Front 17" x 7.5" 47mm offset
-Rear 17" x 8.5" 58mm offset

This may help:
I have the 18" AMG option wheels. The sizes are (f: 18x8, 50mm offset) and (r:18x8.5, 54mm offset). I am adding 5mm spacers to the rear for an offset of 49mm). I had 10mm spacers on, but they stuck out a little too far for my taste.
Also, if you got to http://www.tirerack.com/upgrade_gara...8&autoModClar= you can click on different size wheels for you car in the upgrade garage. If you then click on (wheel closeup, more details) icon, you will be able to see the offset of each wheel. It should give you an idea of how low you safely go.

Too bad the SLK350 16 spoke sport wheels are 18"x8.5" with 30mm offset in the rear.

I had many cars till now but never changed the weels that came from factory,so I am quite newbie in this field.
Would anybody explain what "offset" dimension means and what for are those spacers.
I have the 17" weels on my C220 CDI Avantgarde and I would like wider weels like 18" for a better grip.
So please if someone can enlight me on this subject I will be happy.

This explains it well:
http://www.tirerack.com/wheels/tech/...jsp?techid=101
In the diagram, the wheel has a positive offset, because the mounting hub mounting surface is closer to the street side (face) of the wheel. The distance between the center line of the wheel and the mounting surface is the offset. Zero offset means the hub mounting surface is directly at the center of the wheel. When you move the hub mounting face toward the face of the wheel you have positive offset. When the hub mounting surface is more toward the inside you have a negative offset.
It sounds backwards, but the use of spacers changes or reduces the positive offset in this case (the diagram) by moving the wheel out further. The lower the offset of the wheel, the further out the wheel sits. So, if your offset is 50mm, and you install a 5mm spacer, you decrease the positive offset of the wheel to 45mm.
Now you should play around on this website:
