I want to put the new HID system on my Z4 2.5, but my previous owner said he already did it, but the HID just didnt work properly, anyone have a issue on the after market HID?

Has anyone lowed your Z4, i need some advice.
I am australia and what i heard from suspension guy, he said its very hard job to change the rear spring, is that ture?
