You Didn't Think We'd Leave Our GC Friends Out, Did You?
iDCCD harnesses the power of current technology for a simple install, with serious capabilities.
The 1998-2001 Impreza helped define Subaru performance. Lightweight, mechanical, and connected to the road in a way few modern vehicles can match. The only thing missing from many GC builds is modern DCCD control.
iDCCD brings advanced center differential management to the classic Impreza chassis with a fully engineered, plug-and-play solution designed specifically for GC owners. Whether you're installing a DCCD-equipped STI transmission or upgrading from one of those outdated controllers, iDCCD gives you the control and confidence your build deserves.
Built Specifically for the GC Chassis
Every generation of Subaru has its own quirks, and the 1998-2001 Impreza is no exception. That's why iDCCD is more than just a controller. It is a complete vehicle-specific solution designed around the wiring, mounting, switches, and gauge cluster options found in the GC platform.
We've done the engineering so your installation remains clean, straightforward, and factory-like.

Modern Control for a Classic Subaru
Unlike early DCCD controllers that relied on limited adjustment options, iDCCD allows you to tailor differential behavior to match your driving style and vehicle setup.
Use the iWire Connect App to adjust maps, configure settings, and fine-tune center differential behavior directly from your phone. Whether your Impreza spends its time on the street, autocross course, rally stage, or mountain road, iDCCD gives you the flexibility to make the car feel exactly the way you want.
Designed to Grow With Your Build
The best Subaru projects are never truly finished. That's why iDCCD was designed with future software updates and expanded functionality in mind. As new features become available, your controller can evolve alongside your vehicle without requiring hardware replacement.
Simple Install. Serious Performance.
Your GC deserves more than a generic DCCD controller. With vehicle-specific engineering, OEM switch compatibility, app-based tuning, and plug-and-play installation, iDCCD delivers the most refined DCCD experience available for the 1998-2001 Impreza chassis.
