I don't know really much about them. But what I do know is that they participate in the touring class in the Belcar. This is a Belgian endurance championship, with a huge variety of cars. It's mostly raced on Spa-Francorchamps and Zolder and it includes a 24h race.
VTR racing is the only team participating in a Saab (a 300bhp 9³ Viggen). They have one experienced driver and one novice driver. They're not a really professional team, because it's not there purpose to make money out of racing, it's more like a hobby for them.
Maybe I will have more information when the new Belcar season starts in April.
You should take a look here for a little more information.
