Wow. That's how you feel when you get these up-parts. I you're looking at these then you observably own the FXX kit that Taimya makes and you know the insane level of detail that is in the model, well this kit knocks it out of the park with metal pieces for all the mesh work and grills. But the real stand out is the 4 point harness that is built-in as well as the material to make the seat-belts themselves. The level of detail, quality and the clear instructions are a token of Tamiya and are all bestow in this kit addition. One word of information though, the size of some of the parts you are working with are exceedingly small, even by 1/24 values, so have a good pair of needle pliers handy, and have a good time! - C.
