Are rear wings on FF's really needed? [ANSWERED]

..............All the real life FF race cars have 'em, so yeah, I'm pretty sure they are needed...
Me personally, I remove wings off my cars for that Q-car feel, so there's that....

Eh, but what would a rear wing do on an FF?

Almost nothing.

.........Push down the rear end - ya know, generate "negative lift"?? If cleverer folks than me put those wings on FF race cars, then there must be reasons.....good ones...

Well...

"The trend here is that FF cars both accelerate and turn better with a stiff rear suspension. The trade-off is that they get really twitchy as speed increases. Additionally, the cars want to swap ends in the braking zones because all of the weight transfers to the front tires. This causes the stiffly sprung, unweighted rear tires to hop and lock up—neither of which is good when going for consistent speed and placement at corner entry. If only there was something that would push down on the rear tires at speed, yet lighten up to let the car be agile and autocross-like at low speeds.

OK, let’s get that hand back outside of the window. At 30 mph you should feel almost nothing. At 60 you feel a lot more pressure, maybe twice as much. That’s because when your speed is doubled, the air pressure roughly gets squared. There is no magic number where wings suddenly start working, but mounting a rear wing to an FF car works out quite nicely. The air speed stabilizes the rear end when you need it to, but still allows the front end to really bite at low speeds—when you want it to."

I guess this means case closed, thread closed. Thanks, guys.

Wrong. Check Post Above.

No Problem, glad i helped 👍

Almost nothing.

If you've only driven FF's in GT I can understand how you'd feel that way, they have an unrealistic amount of understeer and no characteristic lift-off oversteer like most modern FF's do, so yeah, in that case, a rear wing isn't needed. Real life behaviour of FF's, especially higher powered race cars that also have front downforce, is quite different.

I use rear wings on very fast FF cars, like the SRT SRT4, Ford Focus RS and Honda Integra Type R DC5. Makes them stable under braking and when the car suddenly twitches at high speeds.
