Porsche 911 964 RWB Kashiwa Blue GT Spirit 1:18

About the Porsche 911 964 RWB Kashiwa Blue GT Spirit 1:18
TL;DR: GT Spirit's 1:18 resin Porsche 911 964 reproduces Akira Nakai's RWB widebody build in Kashiwa blue, its riveted flares and deep front lip cast into one sealed body. Unlike Liberty Walk's bolt-on kits, RWB builds are hand-fabricated one-offs. A display piece for Porsche and JDM tuning culture.
Rauh-Welt Begriff builds nothing off a shelf. Every RWB 911 is fabricated individually by Akira Nakai and his team, and this Kashiwa-liveried 964 is one such build, reproduced by GT Spirit in resin with the riveted arch flares and deep front lip that define the style.
GT Spirit's Resin Cast of the RWB Porsche 964
A Sealed Body Around Riveted Flares
GT Spirit casts this 964 as a single sealed shell, with doors, bonnet and boot moulded shut and no shut line breaking through the widebody's riveted arch extensions. RWB's flares are fixed to the body with visible rivets rather than blended seamlessly, and a sealed casting reproduces those rivet lines cleanly across a continuous surface, exactly as they sit on the real car. Resin's casting tolerance keeps those small rivet details crisp rather than smoothing them into the bodywork, and the deep front lip and rear GT wing hold their correct proportions relative to the narrower factory 964 shape underneath. The front bonnet vents, moulded rather than functional on a sealed casting, still read correctly from the distance most collectors view a shelf model at.
Kashiwa Blue Finish and Wheel Stance
The blue paintwork sits deep and even, with the flares and rivet lines picked out clearly under a shelf light rather than lost in the colour. The wheels sit close to flush within the widened arches, the extreme low stance RWB builds are known for reproduced without any visible gap above the tyre. Badging is minimal, in keeping with how understated RWB builds tend to be away from the bodywork itself, and the rear wing sits at the correct rake for the kit. Wing mirrors carry a satin finish that contrasts deliberately with the gloss body colour, a detail RWB builds are frequently finished with.
Akira Nakai's Rauh-Welt Approach to the 911
Hand-Fabricated Builds Versus Bolt-On Kits
Rauh-Welt Begriff, founded by Akira Nakai in Japan, takes a fundamentally different approach to widebody conversion than kit-based houses like Liberty Walk. Where a bolt-on kit is designed once and fitted repeatedly, Nakai fabricates each RWB build's flares by hand, cutting and riveting them to the individual car in his workshop rather than shipping a mass-produced panel set. That means no two RWB 911s are ever truly identical, even when they share a name or a colour, and each build carries its own quirks from the fabrication process. Collectors who follow RWB closely often collect by build name rather than by generation alone, since the fabrication story attached to each one is part of what makes it worth owning.
The 964 as an RWB Canvas and the Kashiwa Name
The 964, built from 1989 into the mid-1990s, is one of several 911 generations RWB has worked on, its rounder factory arches giving Nakai's team a different starting shape than the flatter later 911s. RWB names its builds individually, often after a place or a person connected to that specific car, and Kashiwa follows that convention rather than referring to a factory trim level or a generic colour code. That naming culture is part of what separates RWB from a kit manufacturer: buying into an RWB build means buying into a specific car's story, not just a style of flare.
Positioning an RWB Build on a Porsche Shelf
An RWB 964 sits deliberately apart from a factory-spec 911, and it works best displayed with that contrast acknowledged rather than folded into a chronological run of standard Porsche generations. At 1:18 the widened arches add a little to the base footprint, worth checking against narrower factory 911 castings sharing the same shelf. For a collection that already leans toward Japanese tuning culture, an RWB build offers a distinctly different philosophy from a Liberty Walk kit, hand fabrication over repeatable bolt-on styling, worth owning as a contrast piece rather than a substitute. Pairing it with a Liberty Walk subject from elsewhere in the range makes that philosophical difference immediately visible without needing any further explanation. It rewards a collector who values the story behind a build as much as the casting itself.
