The S2000 CR adds extensive aerodynamic body work that functions to significantly reduce lift and enhance chassis balance at high speeds. An underbody front spoiler and a trunk lid-mounted rear spoiler combine to lower the Coefficient of Lift (Cl) by as much as 70-80 percent depending on the roof configuration. Downforce is created by the rear spoiler when the hardtop is installed as the contour of the roof is designed to influence aerodynamics at the rear of the vehicle.

 

Are you serious? He claimed to have some information I was not aware of. I've spent a lot of time looking at wings for this car. I was asking for his data. I can't find where I was arguing.

Thank you for providing some links. Unfortunately, you are going to have to help me out further as my searching through these articles didn't find anything. jyeung528 mentioned wind tunnel testing. None of the linked articles mentioned a wind tunnel. The most encouraging line I found was the "Honda claims overall downforce on the rear axle at speed," from Car and Driver. Unfortunately, this a second hand claim of a vague force at an unspecified speed.

So what I claim is that I have seen no data to support the effectiveness of the CR wing. I would like to, but until that day, I can't recommend that another forum member go out and spend money it.

 

hey there.

go to yahoo.com or google.com

type in honda s2000 cr wind tunnel

 

If your looking for max down force get a big dual element wing. The CR wing is good for its size and type but a good dual element wing will make alot more down force.

Best I could find...

"The S2000 CR uses a front underbody spoiler and a rear wing spoiler to further enhance aerodynamic balance and reduce the coefficient of lift by about 70 percent overall with the hardtop removed and 80 percent with the hardtop installed. When the hardtop is removed, the roll bar cowlings help direct airflow to the inner part of the specially-shaped rear wing spoiler to reduce lift. Installing the hardtop directs more airflow to the rear wing spoiler to further reduce the coefficient of lift by another 30 percent, which enables the creation of rear downforce."

Also, when I inspected the spoiler and trunk area, I noticed little plastic braces in the seams of the trunk so that the downforce is applied not only to the latch, but also to 2 rubber bumpstops and some plastic pieces installed on the sides of the lid. I doubt Honda would have gone through all this trouble for nothing.

 

Oh look, more people giving second hand, vague, qualitative accounts. Just like the other searches I've done. Still waiting for some actual contribution here. If this is so easy, just post the magical link you found.

I will have to get some pictures when I get home and post up.

look guy.

you doubted the wind-tunnel statement, so if you did the search, you would find the statements made by various publications on wind-tunnel testing.

no one claimed to have the numerical results from said wind-tunnel testing, so stop asking for it.

 

Sorry buddy, I'm still missing the part where Honda says anything about a wind tunnel. I've done the searches, I've followed the links from these posts, all I see is a bunch of conjecture. Honda does release some generic Cl numbers, but they don't say where they came from. I think you are making a link in your head that doesn't necessarily exist.

I'm not saying Honda didn't do any testing, I just can't find the proof. You claimed to the OP that Honda confirmed this wing in a wind tunnel, so I assumed you had something to back that up.
