I was going to suggest rockauto.com, where I got mine, but on checking, I don't see then there any more. I do see them on O'Reilly's site, oreillyauto.com, for a good bit more than I paid at rockauto a couple of years ago. (Oops, you're not in the US, though...)

It would still be worth it, to eliminate the ever-constant expense of always fixing the system. Arnott is the only one I know of that includes the device to kill the suspension warning on the dash after installation.

Please put a few details of your car model, year etc in your signature so that Forum Members can give accurate help?

For example, if your Jaguar is 2004 or 2005, then you will not need a bypass module; simply disconnect everything at the Air Suspension Module behind your rear passenger seat!

No. their instructions clearly state that the connector is not needed after the conversion.

I don't know of any aftermarket struts that are CATS-compliant.

Default bc racing

I converted to bc racing coils with the Swift spring option. I am very happy with these. These shocks are adjustable both for ride height and stiffness.

Keep looking at Maxpeedingrods.com. They show two versions of the coil-overs. They recommended the track version for a XJR. Fully adjustable for spring rate (ride height) and rebound dampening.
They have air struts too. But either language conversion issues or lack of knowledge on their end makes the active dampening situation doubtful. Says variable dampening, but do not know if electronic, says inductive signal.
