offset MC adapter and MC
I don't have one, but it moves the pedal attachment to the other side of the pedal. Since it's an eylet type its only on one side.
This is the stock location:

So it would end up on the left side instead of the right.
Not sure what Master Cylinder you have now, but you would want one with a smaller bore. It will increase pedal travel to decrease force though.
Dr. Diff sells the adapter and the master cylinders.

The 15/16 I had on my car when I had the stock brakes and it was better than the original one.
