    It's possible to file the wider rotor down to the correct width. I haven't tried it myself, but it should be fine.

      You don't need to file whole rotor arm (you would have balancing problems then) - just the copper part. Just cut ends with sharp file, or metal saw blade. 5 minute job.

        I followed the advice of this thread and still ended up with a rotor arm which measured 18mm!!! Having said that, I did get it from GSF.

        They have now given me one from a Mercedes which measures 10.65mm. The question is, will this be too small???

              It has to have smaller tip for the high rpm...to reduce the spark hop issues.
              Iff the mercedes one has 1kohm resistor...then is ok..
