Advice on suspension for my 2001 bmw 330i sedan

Hey everyone, it's been a long time since I have been on the forums and have recently decided to do some upgrades to my silver 2001 bmw 330i sedan. I have the bilstein sport shocks in there with the stock springs and am running the stock on everything else (i.e. stock m68 rims). I want to upgrade rims and suspsion on the car and am looking for some advice on rims and suspension setups out there.

A long time ago, I like the ZHP or CSL rep rims look (contemplating 18s vs 19s - I currently run 17inch) and would probably look for a rim similar to this style (but open to other opinions!). I also would like to lower the car enough to remove the wheel gap but not give the car a 'dumped' look and am wondering what type of suspension combination would best work to accomodate this.

Any pictures are greatly appreciated too!

Thanks in advance -
