E39 Mpars 18in wheels going on my 92 e32

[Mattie E32]

Hey everyone , I am just curious if anyone else has installed e39 mpars on their e32 , if so what hub rings or spacers or other setup are you running to compensate for the bore size difference. I am.not 100% which option I want to go with or the specific ones I should get . Any help would be appreciated alot . Thanks everyone!

I will move it to the E32 forum, maybe a member there has experience

All E39's have a 74.1mm hub while the E32s have a 72.5mm hub size. You would need the appropriate hubcentric rings. Something like this for example:

Also all the E39 original rims/wheels are an ET20 offset, the same as the E32 so it would be a match as far as offset. There were a few certain set of rims that were not ET20, but not sure which ones those were. You can look at the hub on your wheels and it will have the offset written on there.

I run a set of E39 Style 66 wheels (17x8 + 17x9), and use 72.6 to 74.1mm aluminium hub rings. As Serge said above, the offset for E39's are fine.
I've tried plastic rings, and they're rubbish - the wheels were never centered properly and would vibrate at any decent speed.

Also bear in mind that the rings might be quite difficult to remove from the hub or wheel when changing tyres. For that reason I replaced the spare with an E39 15inch rim, after having to pry off a stubborn aluminium ring from the wheel hub by the roadside.

As much as i love the look of Style 37 M-Parallels, I wouldn't recommend any larger than 17inch for the sake of maintaining ride comfort but it's entirely down to your personal preferences.

Here's the instructions for fitting E39 (or replica) alloys on the E32/E31/E38:

Do 18x8 ET24 wheels fit the E32 well?
