I would highly advise.. do NOT attach that one your car
look at the angle of attack... all your doing is creating LIFT on the front end.
In addition the rear spoiler (whale tail) will increase the rear downforce and create MORE LIFT in the front of the car!
Now imagine driving at 75mph and the car in front of you blows out it's tires.. and you need to swerve out of the way to avoid an accident..
Your front end is so "light" because of the lift, you loose the size of the tire patch in contact with the ground.
This will result in understeer, and the inability to safe your life and someone elses.
yes this is dramatic.. but its true.
