Hi, just want to confirm if the 7 series e32/e38 wheels have correct offset/center bore to fit e34 cars? 16" wheels specifically Thanks
They'll work as far as hub bore - E39 wheels have the larger bore hub. I'm running E38 8x16 ET 23 Style 5s on my E28 with no problems. You can check wheel sizes and offsets here: http://felgenkatalog.auto-treff.com/
Reportedly you may have issues with tire to strut clearance when using the very commonly available 16x8 ET23 wheels used on E38s. You may need a very thin spacer, 5mm or less.
