any other sources for centers besides usa6x6 or stazworks?
i keep seeing pressed centers, and unpressed centers, whats the difference? i hear that the pressed centers are stronger.
what kind of inserts should i get? pvc rubber steel cut down stock or what?
what about valve stems? can i run rubber stems or do i need steel?
thanks in advance.
