The yok does come with flanged bearings however they have a really small inside diamiter since the axle is larger, so as long as you are still running the same large front axles you should be dialed. And stick with Jaco tires for sedan, for some reason alot of the TRC tires for sedan I have seen guys run at local tracks have been really off. They have run TRC sedan tires and there cars have been awful bolt on a set of jaco's and they are dialed (and these are wall banging newbies I am talking about, but racers who do pretty well at big events).

As far as cyan's and granites, if you wanted to run normal tires you could just run double pinks and whites, all of the jaco guys do it, its not a big deal.
