Steering
Hello together,
Special question! Does our cat have speed-dependent servo steering? Even in dynamic mode, I find the steering a bit spongy generelland and compared to the Porsche 911/997.2 much more, and this is particularly noticeable after driving one or the other for a long time. Do you assume that, similar to the transmission or engine, you can't do anything electronically?
Thank you for all answers...

FYI, at some point (2016-2017?), Jag switched from hydraulic-assisted steering to electric-assist. That's all I know about it.

The vehicle is fitted with electric power steering, provided by a ZF Servolectric® steering gear unit with variable ratio, rack and pinion steering and speed sensitive power attached to the steering gear.
The steering gear also incorporates:
A PSCM (Power Steering Control Module), on the end of the electric motor
A reduction gear
A torque sensor on the gear mechanism.
Power assistance is controlled by the PSCM, which uses the electric motor to apply an axial force on the steering gear via the reduction gear. The level of power assistance depends on the position of the wheel and the vehicle speed.
The PSCM also uses the electric motor to provide the following assistance features:
Pull drift compensation
Assistance changes during Eco Stop/Start functions
Assistance reduction if system overheats
Assistance reduction if supply voltage is too low or high
Assistance reduction for system stability optimization
Soft end stops
DC

If you have the Electric (and not Hydraulic) Steering, which you likely do, it is speed and other input dependent. See Below additional Info:

Hi and thanks this is useful to know. I assume there was also a steering control functionnality for the previous hydraulic set up : with my 2013 v6s, I am not experiencing any situation where the steering is spongy as described by Andi jaguar G above, even if the steering could be slightly more direct! Have a nice day all!

I don't know is spongy in englisch the right word! But in a fast curve, the steering is for my feeling very soft and not direct enough. You become a late feedback over the steering, I have not a good feeling and it's not a safe feeling. Not totally bad, but not really good...
#12
I think with this steering is everything good and normally... How different is your steering from D to Dynamic Mode, when the sporty Steering is activated? For me it is I little bit better and little more direct but not really much more better as in D Modus in my view.

That is precisely the way I would describe the steering in the base model that I sold this past July. I brought my concern to the service department's attention at least twice and they reported that it was normal and not adjustable. I would have preferred that the steering at higher speeds in turns was more firm with better feedback. This particular F-Type was driven exclusively in sport/dynamic mode.
And the precise steering, which used to have little feedback, is now much more sensitive.
Jaguar have worked on this problem and the new steering is better. I will test this in summer, hope my Jaguar Dealer have an R AWD :-)

The new F Type R AWD with 575 PS have also a new Steering! In a German Test, following Info...

doesn't simply offer an additional, sportier and more extreme setting option. If you don't want this, you don't have to choose it. But if it does, it would delight all drivers,
including those who want it sportier. The steering is just too soft, even in dynamic mode. Too much play and too spongy in faster passages. Yes, that's scolding on a high
level, but that's the bitter truth. However, the soft steering has already been criticized in many tests. So there must be something to it, it's not just my feeling.

Plenty of us run 21's. Coupled with decent tyres (I have Michelin PSS's) the ride isnt compromised at all from the 19's and P Zeros, so I guess it would be an improvement on OEM 20s. And the steering is absolutely fantastic, in the RWD 6 at least - you point and off it goes, you can really attack corners with enormous confidence. I've had them on for a few years now, best thing I have done to the car. They are quite a bit wider than stock as well, and look great with a nice deep dish.
specs:
Front: 21x9 +32 (265/30R21 Michelin Pilot Sport 4S)
Rear: 21x10.5 +25 (305/25R21 Michelin Pilot Sport 4S)
It's still a bit tail happy, but that is exactly how it should be.
