I'm thinking about switching from my 45 et (fronts) to 30's. Would it be too aggressive? I have a 2011 e550 sedan. Running 245/35/19. Thanks

 

The problem with your question is no one knows - no one will even offer any suggestions because no one has tried it. Three other people asked about offsets earlier including myself with no answer haha. I'm getting some 19" and I'll see how the tire clearance is to run a more aggressive offset. Going down from a 255 and +15 in offset typically wouldn't be a problem except you'll probably be promoting a bit more oversteer and a +15 increase in offset is usually a little bit harder on the wheel bearings but for street cars it's usually not that big of a deal...

 

I'm using 19's w/ 43 et. Using a 10 mm spacer on top of that all the way around. Think you should be fine.

Yosheego, I'm running 30-33mm front offsets - no problems.

EmE247, always meant to ask you: how did you manage to install a 10mm (I assume H&R) spacers on the front hub? My car would accept only a 15mm spacer, as 10mm spacer does not reach the back plate since hub is too high(long) and does not "seat" flush against the rotor's mounting plate.

 

Not sure as my friends shop did the mods. They are H&R 10mm spacers front & back and different lugs.

 

Can you machine down the spacer? I'm surprised you MB guys are running 10-15mm spacers - how much thread do you have on the lugs??

 

There are zero (0) issues running spacers, when you know what you're doing. Am (was) running spacers on most of my current and previous cars.

 

Not sure if I asked you before, but are you running H&R springs or something else?

 

I'm sure you can machine down spacers. But because of the precision needed and the cost, probably just better off buying new spacers. They come in most sizes. Depending on spacer size, you may have to buy new lugs like I did. Ones that are longer and accomodate the spacer.

H&R Sport Springs for the W212. My car sits a little lower than the pics in my profile and in the links below.

 

Don't you have to use longer bolts with spacers?

 

Yes
