HID Help.
 

Hey guys!
I want to put HIDs in my 2006 mazda 3 4d. Since I have projector I am not worried about throwing light all over the road. I want to do 6k. I looked on HID nation but I am not sure what I actually need to buy. There are Hi/low kits and Bi xenon. I would like to know which I need to buy and along with which ballast I need. The slim or standard. Also do I need the relay and canceller?
Thank you for the help In advance guys!
