That all depends on whether you're talking about creating downforce or decreasing lift.

 

same thing idiot. downforce reuces lift so you car sucks to the ground more.

 

No, you can create downforce without reducing lift.

Canards create downforce. Wings create downforce

Spoilers reduce lift. Underbody plates reduce lift. Diffusers reduce lift.

 

nice

 

You can only have them if you've got and Ings kit for your RSX. They look so damn sessy on those h:.

 

how ever i realy want to see how much down force you get off of some thing 3m sticky tape to a palatic bumper with flex wings :-/

 

if ur refering to the canards.... they are on super light gutted race cars...which make a difference.


on our daily driven cars...they are for looks more than anything else.

 

Canards are typically made from CF or aluminum, so they don't flex much, if at all. They're also typically bolted on with L-brackets.

 

you are stupid. downforce IS reducing lift. and diffusers dont reduce lift at all. they direct air flow that goes underneath the car to make it more aerodynamic. f*ckin newb.

 

Let me put it this way... if you add canards, the amount of lift your car has is the same, you just added downforce to counteract the lift.

If you add diffusers and underbody plates, you are reducing lift (and drag) by providing a smooth flow of air underneath the car.


A spoiler reduces lift (and drag) by moving air turbulence that accurs in the wake of a vehicle away from the rear of the car.

A wing creates downforce by using drag to push down on the rear of the car.


Two different strategies that work together accomplish the same goal.
