Advice for lowering 6r without rubbing? Static

Hey everyone,

when end I was younger I had a 9n3 and slammed it, was kinda reckless...

I have  just bought a 6r 2010 and I want to lower it with bilstein b14’s...

I keep seeing such nice examples of slammed 6r’s and it’s making me want to lower it to the max, but I’m not sure it’s gonna be practical and I don’t want to spend the money on bags... 

would my my best option to roll the arches? Or could I still achieve a good luck without? 

I was was looking at some borbet 18” allows but will this be too large? If so has anyone got any examples of nice alloys that are small, I prefer them to be concave as well...

any help would be greatly appreciated,

cheers
