I got the box and certificate from wheel power for it. It was made for any E46 (ex. m3) but I had to modify it by drilling an extra hole to fit my E46 M3 bumper. So there's actually 3 predrilled holes and one drilled hole that I made. I used only 2 predrilled hole and the hole I made to attach it...and the other predrilled hole I used a CF sticker to cover it up. So if anyone has a E46 M3...It's all set for you to attach it on! The only downfall is one of the splitter is slightly damaged/scratched on the bottom but is unnoticeable when driving or eyeing from above. I managed to use a clear plastic adhesive plastic (used to protect the undercarriage of RC cars) to protect the bottom of the pieces. Please make your offer...it's the splitters u see in my sig. Brand new they retail $700-$800.
