Group A Rally Era: When Japanese Cars Dominated the World Championship
Between 1987 and 1996, the **World Rally Championship (WRC)** was run under **Group A regulations** — a set of rules that required manufacturers to homologate 5,000 production versions of each rally car. This meant that every WRC-winning rally car had a legal, road-going counterp

Common Questions
What is the realistic total cost to import a JDM car?
A realistic budget for a complete JDM import includes: auction purchase price, Japanese auction fees and broker fee ($500-$2,000), Japan domestic transport to port ($200-$400), ocean freight ($1,200-$3,000), US customs and port fees ($300-$800), transport to your door ($300-$800), and initial maintenance/registration ($500-$2,000). Add 25-35% on top of the car's hammer price to estimate true landed cost before any repairs or modifications.
What does DCCD stand for in Subaru STI terminology?
DCCD stands for Driver Controlled Center Differential. Introduced on the WRX STI, it lets the driver adjust the center differential's torque split between front and rear axles via a cockpit control, with three settings (open, partial lock, full lock).
What happened to Japanese domestic market (JDM) regulations?
Japanese domestic cars (JDM) were designed for Japanese market conditions — right-hand drive, narrow dimensions (tax advantages), specific emissions (unleaded + catalyst), and specific safety standards. JDM cars are legal to drive in Japan but required modification for other markets. The 25-year rule in the USA removed modification requirements once a JDM car turned 25.
Key Terms
JDM (Japanese Domestic Market)
Vehicles manufactured for sale exclusively in Japan. JDM cars often have different specifications than export models — right-hand drive, Japan-only engines, unique trim levels, and stricter emissions equipment. The term is frequently misused to describe any Japanese-brand car.
GDB (Impreza WRX STI)
The chassis code covering the 2000–2007 Subaru Impreza WRX STI models. JDM GDB STIs featured the EJ207 engine, Brembo brakes, and DCCD driver-controlled center differential — equipment not always available in export-spec variants.
JAAI Inspection (Japan Auto Appraisal Institute)
An optional independent inspection offered at major Japanese auctions where a certified appraiser physically examines the vehicle and issues a detailed condition report. Provides additional verification beyond the standard auction sheet.
