Did anyone have the HID upgrade? Which brand did you guys use and how much and how was it done? Can u teach me the DIY way? I was looking at DDM 55W 5000K from SharpHID.com and Xenon Expert. I was also looking at Xenondepot.com for the XtremeHID 35W 5000K and the ones from VVME.com. Please advise. I know I need a H7 bulb as well...which is different from the older Elises...so I guess the installation procedures are also different?
