I have studied car culture from around the world for years.  In the late 70's and 80's, I remember seeing crazy custom cars driven on the street in Japanese car magazines.  The cars resembled cartoon-style versions of race cars.  The cars had wild spoilers, big fender flares, loud paint, lowered/cambered suspension, and crazy exhaust pipes.
 
I decided to build a slot car version of one of these Japanese custom cars.  Aoshima brand makes model kits and diecasts of older Japanese cars.  
I purchased a beautifully-built Ashima brand Nissan Skyline Kenmeri 4 door.  The seller says it is a Grachen Tribe-style car.  Others have called this style of car  Bosozoku and Grachan style.
 
 
Some Background information on this Japanese car customizing scene from an unclesilvia 2013 post on Datsun and Nissan Owners Club site:
 
"Bosozoku" originates from the motorcycle gangs of the 1950s and the word Bosozoku actually translates into "Violent Running Tribe."
Often guys from these gangs ended up becoming part of the infamous Japanese Yakusa.
Bosozoku biker gangs often terrorized the city streets, riding recklessly and causing lots of noise and disturbance for thrills. This then spiraled into fighting with rival gangs etc etc.
 
In the late 60s and early 70s cars started to be used by the gangs, and, like the motorcycles previously, were often customized with bright paint, loud exhausts and race car-inspired accessories of the period.
 
Since this time, the style of cars has been popular because of the rebellion thinking behind them, however, the gangs that were behind it at the start have pretty much disappeared due to many new laws coming in in Japan. The custom bikes and cars now seen on Japan's roads of this style are now really part of an ongoing "scene" keeping this style of vehicle alive just for the interest and fun value of them.
Grachan Style:
Grachan or Garuchan comes from the 70s and 80s Grand Championships on Fuji Speedway. The Bosozoku used to have big meetings on the parking lots of these events, hence the name. These cars should also match the same bodyshape styling as the cars running on the circuits, with big wide fenders like used on the Super Silhouette styling. These are often the most mental of the Bosozoku cars!!
 
The Build:
 
The parts of the built curbside model were re-glued for slot car use.  Much of the car was originally assembled with rubbery glue.  The interior was sectioned to clear the slot car running gear.  A Carrera driver figure was installed.  Body posts are used to mount the body.
 
I wanted the car to have exaggerated wheel camber.  The BRM brand NSU slot car has rear wheel camber.  The camber is achieved with the addition of a brass universal joint to the rear axle.  I shaved the uprights to increase the rear camber.  In order to "camber"  the front tires, the solid front axle was replaced with two stub axles and the uprights were angled.  The chassis was lengthened by moving the front wheel chassis section forward and extending the guide location with a brass tongue.  
 
I thought about installing a faster motor but was concerned about the life of the spur gear.  So, the stock motor remains.  This one is more show than go.  We will see how it runs.

I remember reading about the "Bosozoku"boys years ago in National Geographic of all places. Love to see some shots of the chassis without the body ... just curious how you get camber on a slot car (although I do spy a U joint in there). Cool build Rodney!

Thanks Larry.  Here are pictures of the chassis.  It is basically a stock BRM brand chassis that has been extended.  I ordered a high torque and low R.P.M. motor for the car.

Wow I thought I was the first person to want to build something like this! Id never be able to do it that well. Im very into the japan scene and these are actually called kaido racers bosozoku is more for the bike side and kind of a catch all term. every slightly different style of car from different prefectures has a different name.

I replaced the stock motor with an NSR motor that has more torque and R.P.M.  The pinion gear was changed from 13 to 10. 

The car runs pretty well.  No tilting when cornering.  Contact patch of the rear tires is only 1/3rd of the tire due to the camber, so traction is limited.  

The front spoiler never scrapes.
