I am setting up a Kyosho GT2 Race Spec for drag racing, and someone I spoke with kept telling me that I should buy a set of "ceramic bearings" and replace all the bearings in the whole car. I have looked through the instruction manual as well as Kyosho's "Optional Parts List", and I am unsure how many bearings to get in terms of what size, and how many of each size.

Can anyone please tell me if they know the different sized bearings that are in a Kyosho Inferno GT2 Race Spec Chassis?
I saw in the manual it has these sizes and from what I counted, this many -
5x10x4mm (6 bearings)
8x16x5mm (12 bearings)
6x10x3mm (2 bearings)

Are these all of them total, or are there differing sizes/amounts?
Thanks again!
