Okay I need some help. I have a 2010 C300 with the stock wheel setup (Front: 17x7.5 ET47, Back: 17x8.5 ET58). I want to get some new wheels and I could not find any answers on other threads in regards to the specifications for the wheels I'm looking at. One set was 17x8 ET40, another was 17x8 ET45, and a staggered setup of 17x7.5 ET48 and 17x8 ET35. Would any of these work? I just want to make sure they won't rub or anything before I go through and get a set. I saw one dude running a 17x7.5 ET40 all around and was wondering if the staggered setup doesn't work, if I could do 17x7.5 ET48 all around. Thanks in advance!

You have all the numbers, so I'm not sure I understand what you need help with. Compare your existing setup to the setup(s) you're considering using simple math, or using one of a million different online fitment sites (like www.willtheyfit.com, for example). Mess around with the parameters on that site and you'll see what changing the numbers does to wheel fitment.
