Answer
Karl,
 I have driven M3's, and the "biting point" was always about the middle.  I would check all the parts to make sure they are for your vehicle, as someone possibly put in components from a different model BMW in there to save money.  If you have replaced the Master-cylinder, slave cylinder, and clutch components, then there is nothing left to be giving trouble.  Unless there is some adjustment to the clutch pedal, like a rod that can be adjusted, or a clutch stop that's too high, I dont know what to tell you.  I know on the E36's they put a Clutch Delay Valve on them, and this is basically a fitting with a tiny hole in it.  This hole restricts the flow of the clutch fluid, so if you were to just "dump the clutch", it wouldn't hurt the drive train, or it would delay the clutch engagement.  Most people remove these as well.

 Unfortunately it sounds like it's a hardware issue.  Like someone put an aftermarket flywheel on the car, and now it's farther away from the clutch throw-out bearing.  So something is making you have to push the clutch in all the way, either the throw out bearing is the wrong one, or the release fork is wrong, or the flywheel is wrong.  Like I said before, make sure someone didn't put a clutch stop behind the pedal, as this could be the problem if it's not adjusted correctly.  

 I would check on these forums for help, there are some really knowledgable people that deal with the E36 on a regular basis (I deal with the E30).
