2) The BRZ HIDs are 4300k, while those fogs are 6000k. Consequently, your headlights will look a little more yellow in comparison to the fogs. You can replace your HIDs with 6000k bulbs to match if it bothers you--DD sells those too. I don't mind the color difference so much, so I still have the stock HID bulbs.

D4S is slightly higher kelvin than D2S (which is 4300K)

I need the brightest LEDs without blinding oncoming drivers. Not sure what to do...
"HP48: 265 lumens. Slightly lower brightness than factory.
HP8: 270 lumens. Slightly lower brightness than factory.
XP80: 510 lumens. Similar brightness to factory.
XML2: 1410 lumens. Much brighter than factory. These are bright!"

LED's aren't going to have the same focus in the housing, and the bulbs are unshielded meaning anything you add is going to simply be glare. It's not going to help you much at night as the light is going to be foreground (meaning you're outdriving the light at any speed above crawling).
