I was reading around on the forums and someone said that the stock spoiler on the ITRs are functional. I find it hard to believe that it is especialy that we have fwd cars...

 

only at high speeds.. keeps the rear end down and from "squirming"..

 

Then technicaly the GSR spoiler should do the same and every other spoiler...

 

i have no technical info on this, but i think the GSR spoiler is less effective..

 

To a much lesser extent, due to the angle/height of the wing. I'm NOT saying that anything taller than the ITR wing would be better. But it is a fact that the higher ITR wing (and different angle of attack) is more effective than the GSR wing, which is much more cosmetic.

It creates downforce, which keeps the rear end planted firmly. It is especially helpful when trailbraking at high speeds (above 80mph or so). It is also helpful at high speeds in a straight line, but not as much as while trailbraking.

 

What does FWD have to do with it? It's not like we are talking about a 1,000+hp drag car here.

It has a great effect on the car when say, braking from 100mph down to 60mph when entering a corner. With the way the ITR is setup suspension and brake wise the car gets very "light" without the wing.

The GS-R spoiler does have an effect, but not nearly as much.

 

Also remeber the that the ITR does have a chin spolier which figures into the equation also.

 

Yes the ITR wing does in fact help with high speeds as far as the down-force of the car goes. Its simple physics really. As to how much more the ITR is then a GSR if any you would really have to do an experiment, one of which most of us know how to do and lack the items needed to do so.

 

I would bet the GSR wing helps to keep the rear of the car cleaner.
also has anyone that has gone wingless noticed if the car gets dirty quicker or less ?

 

The more over 100 you go, the more you need the wing.

Even with the wing, some people have a hard time slowing from 135-145 in a hurry to make a turn at the end of a straight. There can be a brief moment that the car feels like the rear's trying to go faster than the front, and every teeny movement of the steering wheel is greatly exaggerated because of the force coming down on the front wheels.

Jason Franza, Honda Challenge champ in '03, is a good person to ask about this.

When he was coming along in the NASA driving programme, he took his wing off as an experiment, and promptly put it back as quickly as possible.
