F1 2012 - This whole 'stepped-nose' thing

I asked Scarbs himself:

@ScarbsF1 Could you help end and argument - can a team change tubs mid-way through the season, assuming it passes crash tests?

yes, there were rules in 2010 that prevented that, but its been ok for two years now

So, yes it's possible for a team to change the tub mid-season. But the fact still remains, NONE OF THEM WILL. McLaren have commited to the low nose concept for the last 3 years so they're not going to change to a raised nose, especially with low noses being the rules coming into force in a couple of years time. Other teams have all been using raised noses for a similar period and have a wealth of aerodynamic and suspension data which they won't want to throw away unless the rules specifically force them to.

The ONLY way a team will change this year is if the McLaren is massively ahead of the field. I'm talking 0.5-1.0s per lap quicker. Given that the high/low nose pros and cons cancel themselves out, that isn't going to happen.

And Virgin done otherwise

Do you read the virgin link I gave you?

They had special dispensation. It's not allowed, but the fia gave them dispensation as they where a new team (it was in their first year) so there argued they had no existing data on fuel usage.
No one else is going to get special dispensation.

You are just totally wrong, have provided nothing and ignore and suddenly forget stuff a few posts later.
 
If you read back Mr Men was clearly talking about changing the tub during testing. Which is of course perfectly fine, as long as it's crash tested.

The likelihood of a team doing it whilst seeking more performance is quite low though as the risks are just too high.

Virgin were given special permission during the season to change their tub because they were simply unable to complete some of the races due to having a fuel tank that was too small.

Well there you go then.

What's the point if homolgation then.
And why are people like Allan James getting it wrong.

That's right but if chasis can be changed then why have homoginisation. That's the whole point of it, that you can't change it.

I agree but that's why i mentioned the conflict in information. What if homologation is only needed on critical parts like safety cell and suspension, which case changing the chassis could be doable, no?

I cant see the chassis being removed from homogenisation, as that's the main structure and safety cell.
really interested in reading the actual rules on this, why do FIA make it so hard to find. why cant it all be included in the technical/sporting regulations and not septate publications.

But what about homologation of the tub/chassis as there has been a few reports that apparently there is a ruling that states tubs/chassis have to homologated prior to testing.
The only logical conclusion is that both rulings are correct and the tub/chassis is exempt from homologation but that seems a bit odd to me.

Did tweet Scarbs but didn't get a reply.
 
it would be rather silly to say teams cant change the tub after crash testing considering none of them had turned a wheel on track.

They did in 2010 and hence virgin having to get dispensation and all the other teams struggling to implement f-duct.
