E70 30d 20" wheels and arches advice..

[chubbs]

Hi All,

i'm new to the forums and I've just got a 2009 E70 30d.

It's come with the standard 18" run flat wheels and tyres and i'm wanting to change these to a 20" wheel and wanted some advice from all you professionals.

I've found the wheels that I want, I just want to get an idea of what size and tyre I should be ordering?

VERTINI WHEELS

these are the wheels, i'd like them to be staggered, so might I need some spacers?

I noticed that on some of the pictures on here, people have wider arches on there cars, where's the best place to get these? I'm in Australia, so they don't have many places to source BMW parts from. I don't mind ordering these to be shipped over.

Any advice would be great.. hopefully i'll be getting the car looking as I want it...

also i was going to wait till I got the wheels, then maybe lower it a bit depending on how it looks? any advice is great.

many thanks and I look forward to your replies.

cheers.
