yeah, when I have "performance" questions I usually post them on all 5 forums just so I can get a wider range of answers, but as my post count tells it, this is my favorite forum, I guess it's safe to give you guys HERE a rank:
1. United
2. 328i.org
3. Bimmeforums
4. DTM
5. Werkz
That all the forums am on and in order of how much I like them
