Has anyone had fitted or heard any feedback on the RRS Front strut suspension conversion and steering conversion from RRS ?

I am considering this upgrade to my XF but what like to hear from anyone that may have had this conversion done.

not heard of the XF conversions but have heard and read heaps onteh conversion done to the Xy's and older stangs
works a f**k treat and brake upgrades are easy, also you can take the conversion out and restore the car to original if need be
