Rear Forza Aero decreasing PI, increasing performance

As much as I dislike the looks of most of the Forza aero bits, I understand their benefits and how they can drastically improve the performance of a car. Putting an adjustable rear wing often increases handling, braking and acceleration while decreasing top speed, therefore, I feel like the overall impact is VERY positive. Yet the IP drops. How does that make sense?

Also, I found that full Forza aero’d cars are somehow less “draggy” than you’d think and can easily follow non Forza aero’d cars on the straights (benefitting from higher corner exit speed I know but STILL). So that’s a double whammy.

Should Forza aero always increase the Performance Index, and greatly so?
Would we be better off with low/mid/high non adjustable rear wings (and leave adjustable downforce levels to race cars)?

Pic for fun.

Dayum. I honesty thought that pic was of a real life 430 lol.

gran turismo 7 Rear wing upgrade Decreases it’s PP. PP means Performance Points in GT7 on PS5 the game Takes over 130GB of space

You forgot also, it decrease your pi, but you Can reduce the force of the Aero while tuning it for reduce the lost of speed (most of the Time peoples use low value) and the pi don’t change After that, + you can add a little bit of horsepower with the Lost of pi

Usually PI is reduced on lower class cars ( B and lower )but PI goes up on higher class cars.

That’s what makes most sense. On the 430 Scuderia though, which we can all agree is very fast, it decreases the IP by 2 points while front aero increases it by 2.
