Anyone know what those sealing washers are called? They look like a
  regular washer but with a sort of o-ring built into the inside of
  the hole.

  Paul, you should have the spinner tomorrow.

  Brian,
  They used to be called flex-o-seal and stat-o-seal washers. I believe
  they went generic when the patent lapsed.

  Brian, the carbon fiber 16 inch spinner came it. Looks fantastic.
  Weighs nothing. Thanks.

  Glad you can use it. Can't wait to see it in action. It was made by a
  guy named Brian Alley.

  A word of caution on the sealing washers.

 The tension bolt holes have a countersink recess where the sealing
 washer
 goes. This requires a fairly close fit of the washer holding the little
 o-ring in place for doing its job. I can not see how the washers
 available
 at McM can do that.
 I am using those washers on the single rotor, but I do not have that
 recess
 as MAZDA has it.

The correct "tension bolt seals" are available from Mazdatrix.
