RWB/RAUH-Welt BEGRIFF is a Porsche tuner located in Japan.
RWB has combined Japanese and Euro tuning elements,
creating the distinct RWB style for Porsche chassis.
Starting off as a small countryside body-shop in Chiba-Ken,
RAUH-Welt 911’s are now a common sight on both the streets and racing circuits of Japan.
We create only one RWB Porsche for each customer.
