I know little of the evolution (pardon the pun) so its a genuine query
Not much is compatible from one Tamiya car to another. Just the common little stull like ball studs, swaybar ends, screws, etc. Tamiya has a history of making purpose built cars from the ground up.
BTW, the discussion about running foams on the front of the car... I just cut them down with an xacto while they are spinning on my truer. Losing the 2mm I cut off does not hurt handling a bit. Lately I have been running the TRC fronts that are 26mm and they work great out of the box with the standard 1.5mm shims. I tried the other stuff and grinding the knuckles but a)there isn't much material there, and b)you start getting into some illegal widths if you are not careful.
