It seams like there should be some sort of cross-over option to upgrade to bigger brakes and calipers for the E46 M3. Has anyone explored any option to upgrade E46 Front brakes from any later model beamer or porsche or audi etc. The prices for Brembo brakes and calipers seams super ridiculous for a couple of rotors and calipers. Just curious if any has ever seen or heard of a possible match or bracket modifications that could enable a swap of some kind. Seams feasible to me that there would be something out there.
