I'm certain someone has done this upgrade, but I'm having a tough time tracking down info via the search.

I assume there is no need to swap out the master cylinder when doing this upgrade, right? Do the grey Brembos and larger rears require different brake lines compared to the OEM lines on the 30i?

Fronts are plug and play. Same lines, bolts.

Rear dust shields should accommodate the 330mm rotors. May need to bend them a little if otherwise. Gotta check your VIN. BMW has multiple variations of rear dust shields.

Rear calipers will bolt right on.

No need to upgrade the master cylinder.
