Ended up going with a 6000K setup for my 300ZX. The kit was really straight forward and essentially plug and play. There were no problems with the bases on the bulbs or anything they were spot on. Other than mounting the ballasts there wasn't much to it with this kit.

HID bulb vs. Sylvania standard halogen 9006
Illumination is excellent and the bulbs are not blinding and have a distinct cut off line. Its hard to pick it up in the picture but there is very little to no unwanted glare.
