I actually own a car audio shop, but we pretty much do anything. This was our first lambo door kit, but we will gladly do it again. It came out mint, and was profitable. With the addition of 2 H1's and a G wagon to our company cars, we are also getting into truck parts. Wheels, tires, lifts, etc. We lifted our first wrangler this summer. 4" lift with 33" MT baja claws on it. So if any of you guys need stuff, let us know!
