General Forum is a subforum – got it. An order for a car isn’t owning the car – got it.
Even by VW forum standards, this place is a shithole. You can turn off my account now. I’ll use Facebook groups with 2 billion other people.

looks like a good start
Honestly, once blended in it probably won’t look too bad. Will be interesting to see how it works in conjunction with the wing.
Keep us posted
The car is very well balanced now. This is just extra assurance that the front end won’t lift (or maybe an opportunity to increase rear end downforce further, like 12.5 degrees on the wing instead of 10 degrees). It should also run air past the brakes faster.
[quote]Q: And helps downforce perhaps?
AP: A little bit. The more you pitch the car, the more downforce you get on the front axle, and more lift on the back, so you have to find the sweet spot. It’s a little bit higher than the GT3, because of the tyres. It doesn’t show, somehow, but it has about 8-9mm more ground clearance at the front, too.

Q: And the slats in the front wings help downforce?
AP: They don’t only help downforce, they are absolutely doubling downforce. This is such a unique feature, so important. By opening the front fenders, and allowing air to get ventilated out of the wheel arch, we contribute big-time to the front end downforce.
And the problem with the 911 is if you want to create much more downforce and still have the car in balance, you need a certain amount of downforce on the front and the back. It should be one third on the front, two thirds on the back, so making downforce on the back is something for dummies. You just need a wing, you put it in the wind and it presses the car down, but you have to have a counter measure at the front to have a stable car. Otherwise it pivots around the rear axle and you get loose steering, so the key contributing factor in getting that much downforce is that opening in the front.
To give you a comparison, the 997 GT3 RS 4.0 was top of the pops, it was 170kg at 300kph (186mph), which is quite substantial. And this car has more than doubled the downforce, with 350kg at 300kph.
This is exactly the same as the 918 while still maintaining, and this is the big point, the same co-efficient of drag as the GT3, which has 110kg of drag. This is unheard of before, something we are all very proud of, very hard to achieve. And you feel that, because that amount of downforce kicks in much earlier, because it’s a linear function. If you’re going on a normal road, 150-160kph, you already noticeably feel the effects.
Q: So you’ve still got a lot of downforce at much lower speeds…
AP: Exactly. You’ve got half of it at 150kph (93mph), and this is still more than the RS 4.0 had in total. And that’s in addition to the mechanical grip with these very wide wheels and huge contact patches, and that rubber compound, and 9.5in wide at the front with 265s. This is all one big performance plus that is making this quantum leap.
Q: So is aero the biggest step over the GT3 or is it tyres?
AP: I never thought of that, really. The aero is a huge step and the tyres are the next step, but not as much. They are maybe 20% more sticky than the GT3, but the aero is more than 300%, to put that in perspective. I don’t want to bash the GT3, no way, but it’s a different animal, we have different mission criteria. Only a few people want to go to the opera with a wing like that, it’s for a purpose. We wanted a step further with that this time.

I don’t know what made me laugh harder, this statement or the wing on your car. What the fuck are you smoking? 
NEGATIVE KARMA for the “scientist”

I’m aiming for a 14 second quarter mile. So like stock.
That makes -15.
Dude the negativity has to go. I actually enjoy reading your posts on aerodynamics and reading through this and other threads but you and Saki need to work out the banter.
I have to admit the Viper ACR’s street car records at every track I know made me extra curious about aero. This is both hilarious and true:

Angle on the wing is just over 12 degrees when the car is parked. This likely levels out to under 11 degrees under load over 100 MPH, as the rear of the car compresses.
This photo is pretty head on. You can see the side plate aligns with the start of the mirror. The outside edge of the wing creates the most amount of drag and turbulence.

OSIR hood has arrived. Quality inspection underway. I had ordered it April 11. It arrived today with no tracking. Gotta love Hong Kong.
Seems legit. It’s going to look good on the side of the track when it flies off of my car!
It’s so dark I don’t need to paint it black.
WOW it really is nice looking out of the box
I looked on there website to see what else they have and I cant even find your hood on there. Was this a special order .i looked under the A4 section as well as the other sections
It was such a pain in the ass for them to order this one that they removed it from the site. Not sure when they will relist it. I think they have to update the price and freight.
WOW ok that is crazy its cool you got yours. I can see the issues just from the shipping stand point if they dont know when the hood is going to be here that can be hard to tell customers as well.

I dig it what’s the weight savings ?
What is the Y sticker for?
YOLO ;D ;D ;D
You guys were right this thing definitely needs hood pins.
