Could I ask if you have had the suspension properly aligned on your car?

With the jag front end, you definitely have adjustment on toe and castor angle, both of which can have a marked effect on steering "feel".

Dependant on your car, you may have camber adjustment as well.

If you have not had a full alignment done yet, it would be well worthwhile, no, essential, before you start suspecting dampers etc.
As Tom suggests above, setting the ride height up properly is an essential move first, before you set the other suspension parameters.

Your kit manufacturer should be able to give you all the relevant settings.
