the aluminum wings? yes, depending on attack angle and the shape of car in front of them. also surface area, surface area differential (top to bottom or wing profile). there are many factors to this. another problem is that the extruding process leaves a grain perpedicular to the air flow so it will become turbulent and detach the air from the wing some at certain speeds. so painting helps the wing perform and reduce drag. then there is the problem of adding downforce to the rear and not to the front. the wing is also generally not going to make downforce until higher speeds but this is again dependent on flow to the wing. once it passes the stall angle, like aircraft, it is pretty much useless and just acting as an air brake. if you look at most real gt wings you'll notice they are raised in the center due to the different angle of attack caused by airflow over the roof of the car. on dew mornings just pay attention to the water behavior on the rear glass and notice the tapering v in the center that only sees occasional air turbulence that just swirls the water rather then carrying it off the glass.

Sorry to say this but most ricers are honda/mitshu/nissan owners how are FWD. FRONT WHEEL DRIVE. The spoiler will do nothing but create drag unless at speeds of 85-145 miles an hour. Plus the rice spoiler is not engineered with a airfoil shape body that will provide aggressive pressure.

Rice spoiler + honda = less traction

actually you mean wrong wheel drive. and many do have an airfoil shape. if you don't believe me i'll send you a cross section pic of my old one.

however it can help on fwd. when i rallied my camry i used one to try and counter the extreme rear toe at high speeds (80+) on gravel. it also helps the car at low speeds. not that most ricers will ever take the time to work with it or tune it. here's the deal. w/o the weight in the rearend a fwd will tend to get light and floaty around 90+ (yes there are a ton of variables here like body aerodynamics, ride height, etc) and the proper use of downforce will help the car stay more stable at speed. at lower speeds it helps in that you've added weight and raised the rear roll center, both of which will help in that hideous problem the wwd cars have of plowing understeer. so the notion that they are useless on fwd cars isn't true. its just true that ricers have no idea why they put it on the car and what they have to do to get it to be functional with the altezza tail lights.

The fact that most cars are engineered with out spoilers or with the factor spoiler. I doubt that adding a APC spoiler will improve the engineering of the car. The whole point of struts and shocks is not to just provide a smooth ride. But to provide a postive contact with the wheel. Yes a Rice spoiler may have some type of airfoil, but on street cars...is solely for looks and hanging your towel at the beach.

i know they are engineered with out spoilers. but most wwd cars also aren't designed for flogging at 80+ mph either. i noticed a huge difference just in cross winds with mine. i was really curious as to how much it really did. the car stopped "wandering" as much. and i said nothign about apc ****. i don't even bother looking at apc. most that are bought are konig etc. these at least used to have an airfoil shape. and what are you talking about struts and shocks for? as far as i know they are there to control spring dampening. a strut plays a further roll in being an active support in the suspension. if they are pressurized then they add some lift. otherwise explain yourself. i've given the physics behind the uses. sounds to me you are just on the anti-ricer bandwagon and don't really look at picture of whats going on. and as bad proof of some of these working there have been wrecks because some idiot gets a double decker wing and puts too much df on the rear making the front floaty and then pushes right off highway ramp. and yes adding a spoiler "can" help the engineering of a car because that car was designed with compromises. whether someone has the resources or informs themselves with the mechanics to make it actually work is another story. now at least give me an argument more then it doesn't work. i obviously explained how it works. both the theory and application. i even went into other detail aspects of what it affects non-aerodynamicly.

anyway, explain how struts and shocks help combat lift.

Hold on there a sec.

Im not trying to insult your intelligence here.
Im not jumping on any rice band wagon. A spolier can be place on a car an can be tastefull as well as distasteful.

Let me explain the shocks, spring, and strut part for up. When you jack up your car the suspension isn't fixed. The wheels start to proceed downward until it reaches the full travel of the supporting arm. These devices are not just for a comfortable ride, but also to provide postive force between car and road. If we had no shocks and structs and spring. You would airborne a lot.

Adding a spoiler to a WWD car may give u a happy median...but when. You can't just test different spoilers on your car and say...I like this one. Its not like buying shoes.

Now add two and two together.

Adding a spoiler on a WWD car will relieve the engineering stressed and weight toward the front and add downward force on the rear.

Reducing traction and allowing the front wheels to hydroplan easier.

How much can it affects your car. Depends on what spoiler you buy. Not all spoilers come with a lift to drag ratio.

Yeah adding a spoiler may reduce *** end drift, but what I am saying is the shock is suppose to povide a postive contact with the ground. If the *** feels floaty you can put the money into adjustable rear shocks.
