Checked the car (influenced from LFS discord messages) and for me fell 3 things in my eyes that did not seem correct:
1) Slick tyres seem quite unapropriate for such vehicle,not sure if these should be available. Even without testing,from experience with LFS I expect car with such high COG roll easily with grip from slick tyres.
2) LFS cars' default drag is deffinitelly way too low - this car is huge compared to for example XRT,so is it's wind resistance,the theoretical max speed in downforce tab shows 275km/h which is very unrealistic. Since the actual car is limited to 100mph,it was difficult to find out actual possible top speed of this car,the only figure I found is estimation of 210km/h. I would suggest to raise car's drag until theoretical max speed is around 220km/h - with roll resistance of tyres it might get close to the estimated value.
3) Engine brake reduction - why would this car need such feature found in F1 and other high tier motorsports? Does not seem correct to me.
Otherwise (even if I'm not fan of such cars) I have to say it looks like a quality model.
