Im installing 8000k Deep Blue HIDs on my car today. Done with the drivers side. As far as taking off the front wheels is a must. I tried doing it with the wheel turn method and was epically failing.
As far as removing the grey housing and bulb itself its really easy. Ill post up pics after im done. BTW i got the same bulbs the member Westwood has on his Z.
P.s. Hope the police around my area arent to anal bout my lights. Such a PITA just to swap headlight bulbs lol.
