ABOUT US
OUR HISTORY
IAG (Integrity Auto Group) was established in 2004, initially selling high quality used performance cars. Within a year and a half, IAG sold over 200 Subaru WRX / STI’s. Our clients began requesting us to provide performance products and services for their Subaru’s, which we quickly catered to. IAG extended these services and parts nationally by 2007. Fast forward to 2019, IAG Performance is known as a leader in the automotive performance industry (specifically Subaru) and carries an impeccable reputation among our clients and peers.
IAG has two buildings at our original 2.6-acre location at 1203 Baltimore Boulevard in Westminster, MD. The primary building is occupied by IAG Westminster LLC - a car sales business that is run independently. The second, smaller building on Baltimore Boulevard features a complete automotive collision repair shop with downdraft paint booth, prep station, multiple frame machines, spot welders and numerous work bays.
OUR FUTURE
In the spring of 2018 IAG expanded by purchasing a 115,000 sq/ft. warehouse and office space at 1241 New Windsor Rd. The new location allowed us to build a state-of-the-art engine clean room.
In addition to the new engine clean room, we were also able to rapidly expand our manufacturing capabilities. Now featuring new Okuma CNC Mills and Lathes, a Centroid Cylinder Head Porting Machine, and various other machining equipment.
We also expanded our office space to allow room for additional sales and support staff to support our growing product line. Check out our shop tour to see everything inside!

"I've been in love with Subarus since I was about 10 years old. My first Subaru was a 2015 Impreza hatch that I had for 3 years and eventually got into a 2018 STI. That car was a great introduction to the faster side of things, but now I spend time on the trails with my 2024 Crosstrek Wilderness"
