The EPAS Performance System Most cars, trucks, domestic and imports from the 1920s throughout the 1980s can be outfitted with our EPAS System and an easy step by step installation manual is available online for each kit that we offer. No major or irreversible modifications are made to your vintage vehicle, everything is located under your dash and is almost, if not completely invisible. Our Kits can also be mounted on race cars such as road race cars and off road trucks.
