Rpf-1s do come in the 5x100 pattern, but the offset is key. They have very limited offsets. I also recomend this wheel, as it is amazingly light. It is also a very sharp design. Hopefully you realize aluminum or bust here, unless you want to dish out the coin for mags. Chrome is insanely heavy.
Why so big for wheels? Looking for handling?
