Superb, superb, superb, superb mod.
One of the two most high quality and best Formula mods (the other was a 1988 Formula 1 mod) that I have so far test driven for rfactor.
The vehicles engines sound great. They look ultra-high quality and authentic -both the exterior and the interior cockpits and gauges. The animated and visible drivers arms on the steering wheels also makes this mod that much better.
The driving physics are absolutely awesome. These cars aren't too difficult to control; spin-outs and oversteer doesn't happen too often or too easily with traction control set to max; you can control these F1 cars around the race track. Also, the steering is fluid (not jerky) and predictable. The grip and tires provide great feedback as though you were actually in a Formula 1 vehicle.
a general update will come later and I'll check the files
