There’s a weight reduction thread that many of us in this thread provided details and corner balance weights in.

In short, easy to get to with everything mentioned about (bbk not necessary) but once you add a roll bar in it’ll get you just over 3k again.
Keep in mind that a prepared e46 race car (HS or HP with BMW Club Racing) has a minimum weight of 3,142lbs With driver so ~3k lbs is not a bad place to be.
