so you've spent all of that money, and now you want to cheap out on a 9 dollar part?



no, it won't work without some kind of modification. And you are totally right about cutting corners, especially when talking about brakes.

Personally, I think it was dumb to have your rotors drilled to 4 lug considering how easily available the 5 lug swap pieces are, but that's just personal preference. Maybe it was to save you on getting wheels or something. So whatever.
However, it becomes really dumb to cheap out and cut corners when you're talking about such a cheap part. Destroy the fresh powder coat you just got, and modify pieces to save less than 10 bucks.
