Default Is ACI front splitter enough balance for COT wing?

Thinking of doing COT (~57") wing but just curious if ACI front splitter would be enough, or should I do the full ACP splitter/undertray. Car is tracked about 9 -12 times a year and is a dd rest of time. Sent VGLNTE a pm as he is further along in the process but haven't heard back. Thoughts?

very hard to DD a car with a splitter and how hard depends on how far it extends in front of the car.

Looked one up and splitter is not that big. You could run less AOA on the wing. What does there under-tray look like?

$600 for COT wing, $175 for splitter, ~ $200 for installation = aero for less than cost of the Kognition wing. Plus splitter doesn't look like it is that low in the front.

I've been looking at a COT wing also......it isn't very large. Regardless, a wing is tunable, a splitter mostly isn't, so I think you would be able to make it work. I wish the COT wings were 72"

We are putting a COT wing on our GTA type car that is getting re-bodied with the 2011 Howe Camaro body. They are about 57".
The Grand Am wing, also by Crawford is 60". SCCA Trans Am wings I think are 72", but of course the bodies are much wider.

I have a couple extra COT wings.

Honestly, you would think there would be more out there with NASCAR dropping them. I was at Joe Gibbs Racing last week helping them set up the #11 car(not really) and the tour guide said they had lots of the wings in a scrap pile - but she wouldn't tell me where the pile was.

BTW I hope you don't mind me posting the pic of your car. Thanks.

It is a big deal to balance aero if you are not using a wind tunnel.

Best of luck.

If you didn't know what you were doing in the wind tunnel it would be a waste of money I guess?

Probably. So if you have the need, reason, or means to do so I imagine you'd have an engineer who knew what they were doing with you.

What kind of downforce can the cot wing produce at zero and 5 degrees at 120mph? Any data available?

Consumer APR wings are design using CFD and have data about 300lb of DF at 120mph and zero degree as an example and $1500. COT for $600 bucks sounds like a deal and a good way to prep for ST-2 on the cheap.

NASA members get a discount on APR wings of approx 33%.

"I have two available @ 600 each, if anyone can use one."

Crawford has them, but while you could buy them, you could not get them for twice that price 6-7 months ago.
