Yes I know it's balanced and I have heard the drill. It weighes slightly less than stock and has a smaller pulley. So my question is I have a Contitech 6pk 1555 and it's just a slight bit to big. My belt had a split already so I needed a new one.

Which one is the question.

I think Glenn (G.T. on here) has an Unorthodox Pulleys crank pulley on his 98 M3.

I thought Doby had one at some point too. I might be wrong.

I have an OBDII crank pulley from ERT here at the house brand new I never used it....???

Need one???

I have the ERT OBD I unit, found the belt I need. Thanks thou.
