add an aftermarket HID H7 4300 or 6000 kit, aftermarket HID does not need washers or self leveling - i know because i did my previous boxster and it passed MOT after MOT.
I paid £175 via E-Bay and they were perfect, i had the 6K kit, very slight tinge of blue but if you dont like that go for the 4300 kit, they are all about the same price.
Higher temperature ranges are available 8K, 10K and 12K, blue/ light purple and a rather deep purple.
The temperature range is not heat just a light temperature range, All HIDs produce less heat than a conventional bulb, they last 5 times longer and draw only 35 watts per bulb, at night they produce 2.5 times the light and give almost daylight qualities to colours.
I would not use the super white light bulbs as they are 100 watts each, place too much strain on the power circuits and develop a significant amount of heat that will eventually damage the clear lense, plus they dont perform anywhere near true HID.
Ignore the "Zenon" bulbs you see advertised for a tenner or so as they are standard bulbs, true HID come with a ballast and ignitor, dead easy to fit providing you can wire a houshold plug you can fit these yourself.
