Keep in mind I'm doing this for fun, I didn't pay a penny for the calipers so why not give this a shot. Maintaining front and rear rotor size from the F80 will keep balance in check. I have a contact who can make me a front caliper bracket. I track my car quite often so I'll be able to give some input on how the system works on the E9x. I'm assuming a small upgrade in stopping power and good balance. But we will see.

I'll more than likely end up with a proper BBK setup, but anything that allows me to swap pads easier is a plus. I expect the paint on the OEM calipers is probably junk and will burn/change color.

Here are some pics of a quick test fit on the rear (with e9x rotors):
Whats the size difference between stock e9x and f8x? Visually those rotors dont look much bigger.
