Hi,

been using my MY17 R AWD with KW HAS springs extensively and what I noticed is that dampers factory calibration is definitely on the very soft side.
While I can accept that in normal mode it glides and softly bounces on the road making ride VERY comfortable, but in Dynamic mode it is way to soft for truly spirited driving.
In fact I would very much prefer that normal mode would be as current dynamic and dynamic would be 1 step stiffer.

My friend has MY18 R AWD with OEM springs and same opinion. I have never tested SVR but found interesting info about its upgrades vs. R:

The valves inside the continuously-variable dampers have been revised and the control software – the heart of the Jaguar Adaptive Dynamics system4 – has been recalibrated. The overall effect is that both low speed comfort and high speed control are improved.

While the rear anti-roll bar has been thickened, the front anti-roll bar diameter has been reduced slightly. Together with the revised damper control software, a unique tune for the Torque Vectoring system which is designed to enable more precise control of the braking applied to the inner wheels, the changes mitigate understeer – even at high corner entry speeds.

Question to those who had a chance to test drive both R AWD and SVR: did you notice significant suspension stiffness improvement between them?

 

I think it would have been good if they had a "track mode" for the standard R which tightened things up a bit.

I have tried an SVR for a few minutes, but not back-to-back with a standard R to be able tor really evaluate the different. It was back-to-back with a Project 8, which was better tuned for the track than the SVR.

 

No wonder Project 8 setup is superior to SVR...it is few years younger tech.

I wonder what if...I would install SVR front and rear sway anti roll bar on my R AWD.

I was able to find p/n of front SVR but no such luck with rear.
