Those look pretty professional grade, I bet you'd find someone with experience inside a high-end racing team that utilizes simulators. You might try to find out what clients CST has had and see if there's any feedback. Usually a company who's trying to pitch a product on the high end likes people to know that their products are being used somewhere, and will take testimonials from them to put on their website. Except wait, I'd take a good guess that Sebastion Vettel probably doesn't use the RBwhatever Playseat even though he endorses it, so maybe testimonials aren't always what to believe.
