I'm in love.....
I want BMW M3 chrome 18s. They're 5x120. I know there are adapters or some way to do it. Anyone know how / costs /wahts involved? Thanks.

Aren't they like, +35mm offset? How are you going to fit 18x8 +35 under your fenders plus an adapter that will add another 5mm at least?

Haven't thought it through.
There aren't many I'm liking in 5x114, lots of BMW/Benz rims I'm liking.

Can you tell me what would be involved in changing the bolt pattern?

I can't comment on what wheels will fit and in what offset, but it looks like you can get adapters to change the bolt pattern. Try here.

Take your car down to the local BMW dealer and trade it in for a BMW.

j/k Seriously, besides adapters, one way might be to change the rotors to rotors with a 5x120 pattern, or get blank rotors and have them drilled? I'm really not sure, but I don't know how you'd find 5x120 rotors that would fit our hub. Maybe check with a machine shop.

The new rotors will have to be readily available, otherwise you'll be dropping $$$ more than you have to when it comes time for custom replacements.

I may not be doable. There is just a 5.7mm (0.228") difference between our bolt pattern and BMWs. You consider the adapter will have to have holes in the 5x114.3 bolt pattern and lug nuts securing the adapter to the hub and then just 0.228" further out from that bolt pattern is the 5x120 BMW bolt pattern with studs, the wheel and lugnuts. Less than a 1/4" difference is cutting it very close.

It's not a matter of changing the rotors. The rotors themselves fit over the lugs, and onto the hub. You need a complete hub assembly in order to change the pattern of the lugs themselves. That would at least entail BMW hubs, and some way to adapt them to our cars. You could probably have a machine shop, hub shop, custom make you something, but that would probably cost more than the wheels.
