The situation where you'd want low drag would be one with minimal control inputs - basically, pounding down the straight. Hit the DRS button with your left thumb and your right hand is free to shift. When you need to be more active with your driving, you'll also need the downforce so you won't be pushing the button.

You posted the wrong wheel.

Ugh, don't remind me about how I'm going to have to cheer on Ferrari next year. Not looking forward to that one.

Why are you apprehensive to cheer on Ferrari. I can't wait on Formula E.

Because Kimi will be pairing up with FAlonso @ Ferrari. The wheel leafy posted is a joke referencing Kimi.

I have the same dilemma.

mr_hyde 09-20-2013 12:58 PM

Kimi could drive a Honda Civic and I would root for him.

1993ka24det 09-21-2013 02:45 AM

I like Kimi's short answers and the quote "leave me alone, I know what I'm doing'. Then one the next race and gets lost on track. lol

He didn't get lost, in practice and quali the gate was open from that access road. Some track worker closed it for the race, he knew exactly what he was doing.

Having a really difficult time finding a C.O.T. competition wing... :(

Ordered one from Rousch, but what I received was a display wing. Boo.

Has anyone ever found CFD data on the COT wings or done any back-to-back against a GTC-200 or GT-250?

dutchbag 09-25-2013 12:02 AM

I found tons of CFD data of the CoT wings going backwards. Yes. Seriously.

To make sure they dont make lift and flying spinning flipping 2 ton pieces of death known as napcars.

dutchbag 09-25-2013 02:10 AM

Yup. Amusingly enough, the data showed the wing and the spoiler were equally stalled when the car was past 90° from straight ahead. Some papers mused about the CoT demise as being a marketing/political decision. I don't know enough about the sport to surmise either way.

It's a near perfect NACA foil, so the data is pretty available. I will say it's not the best for a car that isn't going 160+ all the time. It's not bad, but a higher incident angle multi-element wing would be much more appropriate for the speeds we're looking for in our tuned Miatas (30-70mph autocross, 50-140 road course).

Yep it isn't the most efficient shape for cars going less than 120 mph but for the price of $300 I could beat buying mine, until I became more serious.

That's what I assumed. It's one of the reasons the COT wing has never interested me - it's not designed for what we do in the slightest.

This type of thing is neat for FSAE projects since active aero isn't banned. I didn't read the whole thread (yet). But...

what was the change in the 100 to 0 stopping distance with the wing disabled and with it active?

If only we all had a spare Peugeot LeMans car floating around to borrow that wing from...

M.Adamovits 09-26-2013 10:01 AM

Believe that's the Peugeot / Red Bull Hill Climb car built for Pikes Peak.

Or did the source the wing for that from their LMS development?

Its an old peugeot LMS chassis with something resembling a production car slapped on top of it. I thought the wing was also from the original car.
