All this talk of FWD cars not needing a wing is a myth, and I am sick of it. Fast cars, regardless whether they are FWD, RWD, or 4WD, will need downforce for the front and rear.
Most FWD cars are very light at the rear, which would of course mean traction is less than ideal . This results in a car that's very prone to oversteer during cornes instead of the more stereotypical understeer (A FWD car? Oversteer!? True story). This is very apparent in high speed corners, where downforce plays a big part. And of course, like I said earlier, better stability under braking. More downforce results in less fidgeting when braking from high speeds. Light rear end+ No downforce + Uneven surface = Loose tail.
Generally, GT wing > Ducktail is simply because GT wings receive less turbulence because the surface of the wing is at a distance from the body of the car, meaning cleaner airflow for the spoiler. Cleaner air flow = effective aero. Unless the car has a sloping roof line, I doubt a ducktail spoiler would be of any help.
I never said front splitter is not needed. It is, however, just one piece of the puzzle. For effective aero, you'll need both front and rear downforce.
All of this, however, is of no relevance to a Myvi/Vios owner with 17" rims with colorful LEDs all around their ride...lol...
Sorry for TOT.
