This is a Custom 1985 Porsche 911 Turbo, nicknamed Kamiwaza. It is owned by Toshiya "Tom" Ichiraku, a close friend of Akira Nakai, the founder of Japanese body kit company Rauh-Welt Begriff, or RWB for short.

Ichiraku, commonly known as Toshi, is the man behind 1048style and the international director of RWB and a number of other companies; he also owns a number of RWB builds, such as the aforementioned Kamiwaza and his 993 named Rough Rhythm. Toshi says he mixed "retro 930 styling with in your face add-ons" for Kamiwaza, and it shows. The car was originally painted matte black but was later repainted to white.

Kamiwaza is fitted with a RWB triple-tier wing, festooned with stickers from RWB owners and his supporters throughout the world. The car's engine has been tuned to produce 300 horsepower and has a spaghetti-like rear exhaust setup. Fitted on 18-inch Work Wheels M1s, the car is significantly cambered and the wheels polished; his car also features numerous sponsors and serves as a demo car for his brands as well as Work Wheels. Given the car's name translates to "God-like", I guess one can say the car does live up to its name.

Now this casting was designed by Jun Imai and introduced in 2019 in the Silhouettes segment of the Car Culture line. This casting has seen three known releases, the last being this one in 2025 after a five year hiatus.

This is a Custom '85 Porsche 930. Nicknamed Stella Artois, this 930 is owned by Japanese automotive tuner Akira Nakai as his personal car. Essentially the poster child of his tuning company, Rauh-Welt Begriff, this 930 is said to be "quite possibly one of the most unique Porsche 911s anywhere in the world". And they might be quite right.

Described as "12 years in the making", this 930 is powered by a Promodet 3.8L flat-6 with PMO carbs, making 360 horses at 8,500 RPM. The car features MSD ignition systems and a trick exhaust system made by RWB themselves. The car's body kit is an RWB design; many parts are made of carbon fiber such as the doors, roof and even the rear wing, with the hood taken from a 993. All this reduces the car's weight by about 800 lb (362 kg), allowing the car to weigh just 2100 lb (953 kg). The car's wing is mounted on a custom FRP decklid.

Painted in matte black and nicknamed after its creator's beer of choice, the car also features an Autometer tach, Momo steering wheel, digital lap timer, RWB-branded bucket seats, fully-adjustable Aragosta coilovers, Endless brakes and either Work Meister S1s or SSR Professor SP1s on Idlers Club Bridgestone Potenza S tires. There's a reason why Nakai-san is so revered.

Now this casting was designed by Brendon Vetuskey and introduced in 2019 in the RLC series. It saw a release in these colors with a figure of Nakai-san, with 12,500 produced, and... that's it. No further releases as of yet. There are some musings going around regarding the state of RWB and Hot Wheels but nothing conclusive can be said right now.
