I have searched and couldn't find much of an answer.... Is it worth to get the conversion wires to go from the D2R to the D2S? My Z is 05 so of course i got the D2R. Does the D2S looks better? would it fit in my 05? Also what would you say 5k or 6k?

 

I'm pretty sure that you will not need conversion wires to go from D2R to D2S. They share the same socket type along with D2C. The only difference is the D2R have the shields on the bulb to reduce the glare created from not having projector lenses in the headlight housing.

As for color goes, most popular from what I have sold has been the 6k.

Hope that helps!
