Sold, Team Associated FT TC5 touring car. Included is a one-way, ITF chassis and top deck (installed), aluminum differential (installed), the hard suspension pieces (installed) along with the stock suspension pieces, and losi shock pistons (installed). Car will come with sway bars and standard plastic pieces used for rear toe-in and differential height adjusting. Just add your tires, body and electronics and you are all set.

Are the original (stiffer) chassis and top plate included?

The original top plate, sure I can include it. Not the original chassis, I am saving that for my son's car.
