That's what I got from the online translators I tried. It doesn't make enough sense for me to guess what @Rucak is talking about. I'm not sure why he'd translate from something else into Dutch though. :-/ @Rucak - post what languages you know. @N7Milla - Frequently when a vehicle gets significantly bigger tires they must be moved outwards to provide clearance for steering and suspension parts. (Since the radius of the wheel assembly is now larger/longer, when you turn the steering all the way to one side the wheel reaches farther towards those components.) The spacers also give you a bit wider track which is usually, but not always, a benefit.
