 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.

 Here they are at McMaster Carr

 Thanks Brian

 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.

they are called dowty washers, here's a link for earls, they are normally
available at your local hydraulic hose shop

email.

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.
