A free bump as well as some clarification...
Both of you are right on the topic. Yes BBK will throw off brake bias but not so much on the E46 330 or 325 etc.
E46 brake bias is, fortunately (or unfortunately for track junkies), further controlled by the consortium of ABS, DSC, CBC and ASC+T. Think of it as a dynamic biasing. But of course one can argue there is a upper bound for the biasing.
Coming from personal experiences, for street or track, these ST BBK as fronts and 330 rear factory calipers will do just fine.
