17" or 18" monos

I recommend that you use these ET figures in making your choice of wheels

So, if I'm reading this chart correctly, the et does change going from a 17" wheel to 18", albeit slightly.
Can those of you in the know verify the minimum et I would need to clear the AMG brakes with 18x8.5's and 18x9.5's?

Since the chart lists et25 for a 18x8.5, if I have a wheel with et30, would a 5mm spacer give me the necessary offset? (I always get confused by -/+ et's wqhen it comes to offsets!)

You can always add spacers do decrease offset, ie making the wheel figment more 'aggressive', bit increasing the offset is not advisable as that would mean machining the mounting surface of the wheel. I mean, I guess it's doable, but one has to be very careful of how much material there is in the wheel itself.
Also, keep in mind that the more aggressive one gets with wheel fitment, and if the suspension is lowered, the more you need to be concerned about wheel and tire clearance with the fender and suspension components. Wheel and tire width is also a concern here, and sometimes even wheel brand and shoulder shape. I had a set of Bridgestones in 215 that were more like 225s in width compared to the 215 Falkens that were mounted on the same wheel previously.
So make sure you do your homework before you spend your hard earned cash on wheels and tires!

Haha, just kidding. I don't know the names off-hand, but just do a quick search for "wheels" and/or check some of the threads that contain the word, "wheels". You'll find plenty of reference to sites that sell AMG reps. Even check eBay, plenty of rep wheel manufacturers there. I nearly bought a set from a dealer there myself.
