    This is genius! Sets up the EM57 for all available B-Face adapters on the market. Great value to use with the spacer and transmission adapter plate you need. Don’t forget to grab the hex cap screws!

  2. RX8.EV (verified owner)

    Great part – and loved that the measurements were all provided for the other half of the adapter!

  3. Michael Murphy

    This was the perfect adapter plate for our Leaf build. It is high quality and excellent value. It also comes with great support from Brat Industries who have experience in all aspects of EV conversion.
