I discussed this with a fluid dynamics professor today, and what you're saying is basically right. The underside of the (inverted) airfoil is more important than the top side when generating downforce, so keeping it free of supports should increase the wing's effectiveness. Hower, the better solution would probably be to place these "swan necks" behind the wing to reduce the turbulence. The regs probably don't allow that though.

Note that this isn't the same mount used in pre-Sebring testing
Any thoughts on the aero advantage the new setup provides? Wouldn't placing the supports ahead of the wing spoil the air hitting it?...unless you purposefully want to reduce the load in the center of the car. Actually, looking at the second pic above, you see that the middle section of the lower element on the rear wing is much flatter compared to the edges.

Nice video, I liked the ambience of it 
Good luck in the race. No wonder the BL GTR servers are crowded by aliens these days

FWIW, I'd like to be using the stick as well, but it's position on the MOMO block is just really inconvenient. I've been thinking about making a new 3 pedal set and probably a shifter (H-gate or sequential, haven't decided yet), so I'll probably switch over when/if that's completed.
Search with Google Scholar. May not be directly related to prototypes, but as long as the papers talk about aerodynamical concepts in racing cars, you could probably get away w/ citing them.
yeah, but McRae isn't using the clutch at all, and Rohrl...he's just a friggin' monster behind the wheel. Right foot braking and left foot braking! I want mad skills like that! 
It's just "nice" 
Yes, they are way more expensive than average PC laptops, though if you want the same form factor, build quality, specs, warranty, etc. the price differential becomes quite a bit less, especially if you have an educational discount or can get a prev. gen Macbook.
To me, the overall "experience" (hardware + software) is much better than on a PC, though that's subjective. And if you only care about "getting work done" and you can get it all done on a PC, there's little point in getting a Mac. Otherwise, try one out.
P.S. agree w/ Shotglass, Lenovo should be on the list. Pretty sturdy machines those.

Don't think this is necessary. You can have your right heel at the bottom of the gas pedal, and under braking you just pivot your foot on the heel to put the toes on the brake pedal, while blipping the throttle either with your heel or with the side of your foot (I've seen both). If you look at some of the "driving" shoes by Piloti, Puma, Adidas Goodyear or even driving mocs/loafers (like Tod's), they have the heel curved lengthwise or spherical, so that it's easy to pivot on. Just thought I'd clarify that.
What Duck may be referring to is left foot braking with revmatching using a clutch button on a wheel, for example. This way you get the best of both - no foot transition time and no wheel lockup (unless you use too much brake). That's what I tend to do, though admittedly I don't have a clutch pedal (I'd like one), and, more importantly, I'm not fast at all.
As far as LFS vs. IRL driving, I don't think this practice affects it much. I don't get to drive much IRL due to a lack of car, but all the cars that I do get to drive occasionally are automatics. So in theory, they'd be perfect for left foot braking, yet I always use the right foot. IMO, the frequency, intensity and braking precision required in most day to day driving is not comparable to what you need in LFS. Couple that to a different driving position, weight of controls, accelerative forces, etc. and your brain shouldn't have a problem transitioning to a rfb setup.
Paddle or stick sequential shifter (GTR)?
For those of you that don't have/use an H-gate shifter, but have the option of using either the wheel paddles or a sequential "stick" like on Logitech MOMO, which method do you use? And particularly with regard to the GTR cars (incl. FZR since you don't have a H-gate). I'm wondering because IRL GT cars have the stick shifter (i.e. http://farm1.static.flickr.com/81/282833809_7e0522cdee_o.jpg), so that's more "realistic", but to me the paddles are easier/quicker, since I can keep both hands on the wheel. I do use a clutch button with this setup for rev matching.

Good read, guys, very enjoyable! Keep it up and best of luck in the race!
Dark FTMFW! At least 70% cocoa, though! 
Canon vs. Nikon?

Meh...This TF109 thing is rather ungainly. F60 looks so much better!
And yes, I waited for the premiere and got jack shit at 12:00 CET. No surprises there.
P.S. now that it loaded 18 mins later, the trailer with Trulli and Glock is kinda fun.

Some recent stuffs
Motorcycles (I got kind of hooked on shooting bikes in motion)
And some stuff that's more or less stuck to the ground

Depends on the look you want. You generally want lots of DOF in landscape mode, and given that it's bright (and the light hitting the camera sensor), you may need to use a fairly fast shutter speed, but shoot in Av. If you do want to use a slow shutter (e.g. to blur water), then maybe adjust your exposure compensation to underexpose a bit. Or if you have some grad or polarizing filters, they may darken the scene enough. Just get out there and give it a go!
Holy noise management Batman! This is friggin' impressive. I would maybe get this level of noise at ISO 400 on my 20D, but I don't even dare venture into the 1600 territory. These new cameras... 
Oh, and f/1.4 is mighty nice, too

No subscriptions currently. Read all the car mags online (Winding Road, Driver's Republic, Motive). Would love to have Evo or Car, but they're ridiculously expensive here.
I also thumb through Racecar Engineering at the library every now and then.

Who's request? I'm a legit S2 user...
That's a really neat idea. Well done and congrats!
