this is a two part question. first, i stumbled across a website a year or so ago that listed all the wheel options available from bmw along with the models and wheel weights. does this sound familiar to anyone? second, the reason i'm looking for this site, i'd like to compare the weight on 17" and 18" wheels. does bmw make a lightweight wheel (or at least lighter than normal stock wheel)? as i continue to mod my car, i want to keep it looking as stock as possible.

thanks,
scott.
