OK here is the question. Take a car like the 458.. You can purchase front spoiler and extensions.. But if you dont have a rear spoiler on the car you cant see if you are getting the +5 downforce on the front cause there is no meter. It dosent show downforce in the tuneing garage unless you add a wing. So here is my question do you get the benefits of front downforce without haveing a spoiler on the rear. I ask cause when you add these features no PP is taken away. Only when you add the wing is PP taken away. And it dosent matter if you add just the rear wing or all the stuff front spoiler rear diffuser extension ect. It still only takes away the same PP amount.. So it might look cool but unless you have a rear spoiler are you getting any front downforce with JUST those item on the car and no rear spoiler..
