bolt pattern is 4 X 100. Not sure on the offset but I think its +42mm, dont quote me on that. I got my wheels from a member on here who was having a big special. I think his name was cashiouseg or something like that. I dont think I have it spelled right. For the all amber bumper lights, you can either get some glass stain and do it yourself, or you can order them from www.autosonic.com . Thats where I ordered mine from because I couldn't seem to find the glass stain. The fitment is perfect. If there is anything else you need to know, feel free to PM me. Oh, my wheels could be for sale if your buddy wants 15"
