You will love the M3s, I had them in my Z and it drove like it was AWD.

 

The M3's are installed. So far so good. I drove on some icy road this morning and it was far better then the summers. and I went through a parking lot that had old sloppy snow and I cruised right through, no sideways sliding. Happy so Far.

One Issue (maybe) - well actually I'll post to Tech section my question.
