I was trying to find some info regarding crankshaft runout and I ran across Hemrick Performance. They have some great write ups on a lot of questions that are asked around here. Just take a gander on the left side, a pretty good selection of stuff. I may look into their HID set-ups. People run them alot here in Europe and $200 for all 3 lamps on an Ultra doesn't sound bad.
