It's been a long time since i've taken a spin with this mod. Took a few laps on the server with the Shadow. It felt really good to me. only two issues I had with the Shadow is that the mirror position was "off". I think they were pointed too low. And then, I'm not sure what it is called, the rF H-Pattern shifting. If you don't let off the gas long enough to shift, the car would still accelerate, but at only half a gear. If you let off the gas, with out changing gear, it goes back to normal. I hope that makes sense. I'm not sure if this mod uses the new GearProtection shift settings, but I think the way it works with that is a bit different, and more realistic. I haven't taken time with mods that have that implemented.
Other than that, it is coming together pretty great. The group 7 cars are great to see in game. If you want some more inspiration on a few cars that aren't in other games (or very rare), Japan had a group 7 scene for their Japanese Grand Prix. I thought these cars were a bit newer but they do fall into 1970:
