While simple solution (if they don't need to change the shape as was also rumored).

It is really weird they would do this for Germany when they only have to do it from Turkey. Even if the generated downforce is similar it gets generated 3 cm more forward. So multipllied by the arm there will be a difference. Maybe they will just use it on one car on SD and then change back?

I went back to the vids from Turkey test and it seems the wing is in the new position there as well (I only checked two Tänak vids.).

Seems needless to change it before they have to.

Looks like they are using this on other cars as well.
I went back to testing vids from Greece last week and it seems Latvala (at least on first runs) didn't use this but later Tanak used it on all runs that I saw. In testing for Germany (which was before Finland) the used the old position.

Also it might be that the "plan" by FIA that all teams need to be compliant by Turkey is multi-step and requires some changes already in Germany?

or that 3cm makes no difference in performance so TGR is using it now.

or that 3cm makes no difference in performance so TGR is using it now.

If it makes no difference for downforce and drag then why were they using the position 3cm further back before? It seemingly only has disadvantages otherwise:
- higher polar moment (more weight further away from center of the car)
- (attachment) need to be stiffer/stronger/heavier cause it experiences higher forces and is more likely to break off

But off course it's an option that the diference is not very big, since the times of Lancer WRC 04 (http://m.webwombat.com.au/motoring/n...rally2-big.JPG), just about anything is possible

Toyota has made changes to the positioning of the rear wing on its Yaris WRC, following a World Rally Championship rules clarification by the FIA.

During the Rally Finland weekend, the FIA said a clarification of rear wing measurements was necessary, while stressing that no car in the championship was running illegally.

Toyota's rear wing aerodynamic specification had not changed since the 2017 season when the current regulations came in.

Toyota Gazoo Racing team boss Tommi Makinen told Autosport: "There are some small modifications, it's basically completely nonsense work, I would call it.

"It's some extra work for us, that's what it means.

"Somebody wanted to make our lives a bit more stressful.

"A bit more work for us, that's basically what I can see."

A team spokesperson added: "The situation is quite clear from the FIA statement.

"There's a clarification in place which comes in for everybody for Rally Turkey.

"In the meantime there's been, as part of the clarification, let's say new definitions on how measurements are taken.

"For Germany, we have the same assembly on the car, the aerodynamic profile is the same that it has always been, but in order to meet tolerance in clarifications there has been positional adjustments in order to meet the tolerance."

Both Makinen and the team spokesperson stressed that Toyota's main target in making the changes was for safety.

"When you do some modifications, I wanted to make sure it was reinforced and strong enough in case of any risk of some failure, it could be very dangerous," said Makinen.

"I understood they [the Toyota engineers] managed to make it without any question about strength."

The spokesperson added: "I think the safety point of view has been our main point since everything was raised in Finland, a lot of work goes into not only the aerodynamic profile of the car, but what is the aerodynamic loading on the car in different areas.



"Now, in current regulations of the WRC, consideration of aerodynamic loading is a significant factor [for safety].

"In terms of what's been done in the tolerance side for Germany, we don't see any risk.

"All the parts are as per they have always been just with some adjustment in position.

"It's been done to make sure we are with the same level of safety we have always had."

Speaking during Rally Finland, FIA rally director Yves Matton had insisted that the rules clarification was not aimed at any particular manufacturer.

"There is no story about the Toyota rear wing," Matton told Autosport at the event.

"There has been a clarification concerning the rear wings from the World Rally Cars.

"We have asked all the manufacturers to do the work, and put them in conformity for Turkey.

"There is an action plan that we have asked all the manufacturers [to comply with]."

Doesn't shed any light as to why they did it for Germany. Only possible "hint" is that the "clarifications on measurements", ie. the 3cm overlap had to be done already for Germany.
