I am considering putting BMW OE style 32 8Jx17 et-20 part number 36111092961 on my stock suspension, stock ride height e34. I also have recent front Boge struts and upper contol arms with 750i bushings. I understand 235x45x17 tires are a size correct match.

As these are e39 wheels I will need hubcentric rings. Plastic or metal and best source?

Will my ride change a lot from my stock 225x60x15 wheels?

Will I need new lug bolts?

Does anyone see any issues for these wheels. For example, will hubcentric rings solve vibration/balance issues? TIA
