Hi Guys

Just a posting in regards to different wheels in J and ET fitment.
Im Looking at BMW x5 Alloys. Not the Staggered ones with 9j front 10j rear but with the same J and ET front and rear.
So the wheels in Question are 18" 8.5J with 46ET front and rear ?
Also looking at a set of 19" 9J with 48ET front and rear ?

Will these fit with no scrubbing with out Spacers or the like ?

I know I need spigot adapters, but in no way will I ever run wheel spacers because I've seen things go wrong first hand from those doggy things.

Oh and my vans a LWB 400TDI on factory suspension if that makes any difference.

Thanks in advance!
