is the steering rack at the same height and with a lighter car you will need a bit more caster than the jag it gives moor straight line stability but to much makes the steering heavy ,the power steering rack needs the pinion welding solid it has free movement in it that operate the hydraulics this will make the steering feel vague,

the jag front end also runs to much ante dive and because the a arm pivots tow out this affects the front stiffness in a corner by making the bottom arm pivot run parallel to the chassis instead of pointing down at the front you will reduce under steer
