Thank you all for your kind comments.
The_GLL, the roll cage was included in the kit! I only added the padding!
And it is an Hasegawa kit (an old one by the way)!
Willimo, you're absolutely right regarding the smoothed door handles. This project stared as a riced car, but eventually turned into a track day car!
The shifter was scratch built from leftovers, bits of plastic and copper wire.
The license plate came from an accessory pack from AOSHIMA. I only applied the decal on a thin metal plate, cut to the dimension of the decal.
stevenoble, yes, it is a Nitrous Oxide bottle, which came from the same accessory pack as the license plate (as the dials in the instrument panel, btw)!
kyuuketsuki, the blue is Tamiya ts-19 Metallic Blue.
Cheers
