And I've always said that of all the drivers I've worked with, he's probably the most brilliant. If Lotus can build a competitive car, Kimi could surprise this year.

Interesting. He's worked; let's not forget; with JB; Hamilton; Nando and Hakkinen

THe rear ride height is 80, not 60.

As to why you'd have toe settings as they are, presumably they compensate for geometry change under load so that under braking the fronts are parallel and under acceleration the rears become more parallel whilst not risking going toe out and have the car get squirmy under throttle out of the corners - particularly as there'll be some lateral load early in the acceleration zone as the car moves away from the apex...
If you are more fortunate than others, build a larger table not a taller fence.

Has anyone ever doubted Kimi's raw pace in an F1 car? It's his attitude that draws the comments...

No really; zoom in massively. It's 60; not 80. It LOOKS 80; and if you zoom it massively and squint hard enough; THEN you'll see the 6

Fascinating shot anyway, does anyone know for certain what "PPS" is in reference to, obviously something hydraulic,
might it have something to do with reactive ride height? If so, the area 4.960 mm^2 and 6 cc volume is most interesting,
when that translates to a 25 mm diameter with a 12 mm displacement, pretty close to the numbers myself and an inactive member has been toying around with.

A quick guess would be a push-pull solenoid which would make sense as a possible component for the RRH system. Of course the devil's advocate stance would be that you could probably stick a PPS in any number of places on an F1 car (or maybe my first comment was the devil's advocate stance, who knows anymore).

Edit: It would make a bit more sense for the RRH internals to be in the Brake table but I could see it going both ways.

I do wonder if Lotus really have a set of Ferrari-style sprung anti-roll bar linkages or if they just put that on the sheet for looks. (I know Ferrari didn't invent it but I think they were the first in F1 to have it and I can't recall the LMS team that I think developed it).

Also, the castor value, that can't be degrees, right? To my mind 12 degrees seems extreme.

Roughly, what is the suspension setup?

There is an outer spring specified but no outer damper.
There are center dampers but no center spring. What is a center system?
There are roll dampers.

That is the possibility of a three types of dampener systems per each end of the car (not just three dampers). What would that look like?

Some of the adjustment numbers might just relate to the shim stacks the mechanics would use to adjust the control arms positions.

Could the PPS information relate to the size and volume of the gas pressurization cylinders found with the shocks?

Oh, good idea, I wasn't really sold on PPS being part of the RRH but it makes sense as part of the damper system since they don't list any details of the internal fluids for dampers (as you would expect them to).

I don't know how they would work in the damper system since they only list one per axle but I don't fully understand the cross-linked Merc damper system either!

Done all that. It's 80. :wink:

From his interviews, the Iceman seems a bit more focussed on the task than I remembered him being, and his feedback is more interesting to listen to. Just my perspective.

PS. I didn't realize I missed seeing him on the track.

i'm pretty sure the static toe settings dont fluctuate much with compression/extension. i'm under the impression that these are typical toe settings for these cars.
