After Mercedes introduced a thorough upgrade package in Monaco, Ferrari seem to follow suit by debuting a raft of new part at this weekend’s Spanish Grand Prix. F1Technical's Balázs Szabó reports on Ferrari's latest development push.
A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.
There is no doubt that the suspension itself is higher than last year. Like i said yesterday - its clearly visible at the pick-up points at the front.But your new images show that they probably indeed lowered the rear lower wishbone for more anti-dive. Testing will give us better images, so we can finally discovers it this is a pic-up point for the rear lower wishbone, or something else. But you might actually have been right in relation to the lower rear wishbone.

There is doubt. Looks the same to me. The change in position of the tie rod playing tricks on your eyes I think.

Possible, but I believe it less - Giorgio Piola has reported the same at motorsport.com - that the front suspension wishbones were raised. Giorgio usually is very precise about things like that.
better view on front suspension. Here it's visible sloped arms. Both, top and bottom wishbone
Beautiful shot.
You can see how the cameras are aligned with the front upper arm.
Zooming in, you notice the brake cooling duct going downwards, the small vertical air intakes under those of the sidepods, then the entrance to the Venturi channels and the shape of the flow diverters in that area, the tea-tray, and... everything...

How exactly does that "antidive" arrangement like we saw on the Red Bull impact performance?
Hard to gage how much of the RB18 characteristics can be tracked to it...
Straightline speed? Probably not, but if the rear is squating more than the front with speed(downforce) it could help.
Slightly understeery? Probably had something to do with it, if they had a front that hunkered down under braking it would certainly mean better front end grip.
On the other hand, it may not have been as gentle on the rears during a stint.

Its not 'antidive' unless it's the upper wishbone canted backwards compared to the bottom, a lot of people keep making this mistake.
Canting both wishbones backwards together is actually pro-dive.

Depends exactly how much they had before tbfh. Generally with more anti-dive you'll trade for slightly more initial grip on hard braking, better control of the aero platform on the brakes as the car will stay more level, at the expense of suspension compliance, especially if you're anywhere you need to trail brake over a kerb, etc.
You also get less feedback for the driver on what the car is doing under braking (see Ricciardo struggling with any car with a stiff setup for the aero platform since RB), you can also get high frequency chatter that makes it easy to lock a wheel as the tyre and suspension get in a feedback loop near the limits.
Plus depending on your aero platform some dive might be a good thing to bring the aero CoP forward while braking on the entry into a corner. Some cars of course the dip in ride height or bottoming might be more of an issue so you don't want that.
It's not really a case of more is better for any way you go, it has to be match to the characteristics of your car and your aero, and even a little to your drivers preferences, that's why you see teams tweaking it every year instead of leaving it on one 'best' setting.
It's also why most people laugh when people claim someone like RB or Merc or similar found some sort of magic bullet with anti dive canted wishbones or PoU type stuff. The answer depends on the rest of the car, not looking at it and going 'that looks better'

All the F1 cars are, they all run antidive. The trick there is how much relatively. They might have canted both wishbones and actually ended up with less AD, not more. But a lot of people seem to just see a tilted wishbone and start exclaiming it's some sort of magic anti-dive philosophy like happened with RB the other year.
If you just took two parallel wishbones and rotated the rear links downwards to angle them. You'd end up with pro-dive, not anti-dive, because of the kinematic wheel recession.
