So i get the GP thunder 8500k today. I just installed them and um. Forget about it. haha They took awhile to ship because I guess they did not have any in stock. The build quality of this particular batch is horrible. I guess u get what you pay for. $12 per pair for GP Thunders vs $25 per pair of Mtecs. Either way, I give up on the angel eyes. HID fog lights are next. Wish me luck
