Very hard for me to swallow with that big honking spoiler on the trunk myself. Now if it was a 3 incher I could see loosing rear grip. The problem as Logano sees it is that the cars can't follow right behind each other, passing on the right has improved, but too much turbulence when behind the car in front when following closely is the problem as Logano sees it. The cars aren't sealed to the track anymore and they depend on air flowing UNDER the car for much of their downforce, so turbulent air would really affect the frontal down force (tight) because the car is off the ground and down force is lost when closely following another car
What you're quoting Logano as saying, Harvick said the exact same thing during the podcast too.

As far as you finding it hard to swallow that the rear is lacking grip even with the big spoiler, lots of sideforce is gone now with these symmetrical bodies plus the shorter sidewall tires are giving less warning as to when the car is about to come around (per Dale Jr, Briscoe). Not to mention it's kind of pinnacle armchair quarterbacking for anyone on here to listen to what driver with 119 wins across the top three divisions has to say about the car's handling and go, "I don't believe him". You're probably talking like the NASCAR execs do after they hear the driver's feedback too.

I'm a bit confused tight means you lose the front, not the back

The reason why Logano and others are saying the car is not turning when following another car is because they are having to mechanically set the car up very tight to begin with, tighter than this past year. Why is that? Because the car's natural tendency is to oversteer and spin the rear, due to the lack of sideforce. Harvick said this on the Dale Jr Download. Let it be known that I am indeed hanging onto Harvick's words because I personally trust his feedback but that's my personal decision and your mileage may vary.

So because the car wants to spin, they tighten it up just to be able to run by themselves without spinning, and then when they follow in the wake of another car it gets super tight, too tight, because the car isn't rotating at all and is just planted but now with no downforce on the nose. But it all begins with the car being too loose to begin with.

Exactly. They have run front springs in the rear & rear springs in the front for 20 some years. Gonna have to get used to doing things like 1990 again. 1800lb fronts/350lb rear springs. Maybe smaller bars. It's all new to them. Won't happen overnight.

The "trunk" is so short and greenhouse so long I suspect the spoiler doesn't have as much effect as some think. Gonna need Swartz to build a car.

The mechanical engineers have them a little slower than last year’s car.

I wouldn’t worry too much about that.

Yeah Nascar said, I can't remember who said it, that they were disappointed about the speed, but that is easily fixed. Tire compounds might be something they are looking at for more overall grip and then there are many adjustments the teams can make front and rear now. I'm not worried either. The car will never be perfect, but it gets better with every practice session.
