IAG Performance
Integrity Auto Group was established in 2004, initially selling used high-performance cars. Many of their clients started requesting that they provide performance products and service to their vehicles, and there they began their engineering and fabrication practices. IAG has rapidly grown, and today it operates out of 2 buildings with over 20,000 sq/ft of production and shop space, using state-of-the-art equipment to develop performance engines and parts widely utilized in some of the fastest Subaru vehicles in the world.
