Unsprung weight is the enemy of all race cars - do you really think that MacMerc would bother spending $1,000 USD per super light weight wheel nut and vast sums of money on wheels that are so light and fragile that they frequently fail when putting a tyre on them and cant be used more than once only to add unsprung weight back again?

I dont and just like last year, the wheel fairings will vanish once testing ends!

I'd gladly trade a couple mm of track, and however many grams of unsprung mass, for the aero benefit of capped wheels. Significantly less drag at speed. Slightly less lift as well I believe.

I believe the outter fairings are sensors of some sort and that the inner ones are here to stay thats if they're leagal, sorry for my igronance as i'm not fully aware of the rules.

Spoken like a true internet engineer. Because he doesn't think they will be there, he feels that he can argue up and down that it is the truth.

Dude, if you phrase that stuff like "Well, I still don't think that they will be there in Aus..."

Once again, the definition of bigotry. Is it really fun?

Ah yes, when a logical argument comes out on top and you dont agree, insult the poster ... classy! [-X

Logical arguments when you have zero basis in reality, and are by definition bigotry. Instead of getting all pissy, how about you increase your vocabulary, take a more modest tone, and not make factual statements unless you have something other than your personal speculation to base it upon. Don't serve your hypothesis as fact. It shows ignorance, and bigotry.

I'm sorry if you didn't know, but it is time to grow up, and back up your statements with fact, not fantasy.

Best regards. I guess this explains why I'm not at my post!

Grow up yourself, if the fairings provide the level of Aero benefit you and others believe, then why has no other team bothered running their own versions of the McLaren fairings despite this concept being around for more than 12 months?

I'll tell you why, they are only good for testing purposes as a sensor package; im sure all the other teams have looked at them and rejected them as being too heavy (unsprung weight again) and not enough of an improvement over the more conventional wheel covers to be worth the weight and track width penalties.

McLaren would hardly have spent time on the outer rim extensions, moulding them into and *improving* the brake cooling flow if they were going to ditch them. They are here to stay, a full integrated part of the wheel setup. Accept it a move on, it's really not that big a deal.

I can give you one more good reason why the outer ones wont be raced; Pit stops, those would be a royal PITA to get off and back on compared to the current rim shields.

Exactly my point, have you watched the wheel gun guy's handling the current ones? The circular nature allows them to spin behind a clear Perspex shield while the gun is fixing the wheel nut, once this is complete they rotate the wheel rim in to lock it in place.

Im sure it's possible to do the same with the one currently in testing but would make mistakes a lot easier under pressure situations.

If anything these are easier, they clearly only face on direction so theres a smaller chance of them going on wrong. This is a Formula 1 team my friend, you really do think they are a bunch of clueless amatuers don't you? So when is the djos F1 team starting? I hear you'll be the engineer, driver & CEO! :lol:

Seriously though, there's only one sure way to find out if these things will be on the car come race day. Someone needs to go measure the front track width... I nominate you! :D

Design-engineering mistakes are made all the time even in F1, remember Ferrari's twin-floor, Benetton's front-wheel differential-something, or McLaren's entire 1995 car?
Personally, I am intrigued to see Renault changing nose and Red-Bull the rear suspension.

Yeap.

Just like when they add brake ducts, outboard brakes and the initial wheel fairings.


Everything is a compromise - they compromise unsprung weight already with the three aforementioned - why would <0.5 kg of CFRP be treated any differently?


The outer fairings are of little interest to me, its the inside ones that I'm talking about.



(I hope this doesn't come across as condescending - thats not the intention) Just don't dig that hole of yours too deep - it just makes it harder to climb out of eventually - I know, we all do, we've all been there, seen we're wrong and done the humble bit. :wink:
