I believe the numbers presented for this car and design. The choice by Alfa is very sensible - the car doesn’t have a lot of power. A bit of downforce (so slightly better than zero lift) and good ground clearance make a lot of sense. Most aero besides underbody is going to increase the car’s overall drag and thereby harm top end acceleration.
To get more downforce I agree that, aesthetics aside, a big rear wing is not a good idea for a stock powertrain due to the impact to top end acceleration. Increasing power changes the story there.
If one wants a lot of downforce for track performance with a nearly stock engine power level, I think the right approach would be to get a very stiff suspension setup and drop the car low so you can maintain a very low flat body position, get an aggressive front end dam, add barge boards, and make the floor fully flat and feed a longer and more gradual rear diffuser with larger openings. You’d gain meaningful performance across the board with very little drag penalty.
But on the street, for me that would be too low and too stiff. Great for a race car.
