Also, I haven't seen the charging system addressed. All of these pulleys must underdrive the alternator as well? I know the M3 charge system is already very weak.. just spent $500 on a new battery.
I've had no issues with the AA pulley. I also run two amps and a sub in the trunk with no battery drain issues.
