Hi everyone. I recently bought some brembo M4 calipers for my CBR 600 RR 2006 track bike. I'm upgrading my brake system and have a few questions that I'm hoping someone will be able to help me with.

I have the 220A39710 model M4's. I plan to upgrade the discs and master cylinder. For the master cylinder I'll use the RCS 19.

Do the discs need to be brembo serie ORO 320mm instead of the 310mm discs which come on the 2006 600RR. Will they require spacers too?

When changing the brake lines (I currently have HELL) lines, will they require a new set specific to the M4 model?

Really appreciate any help. Thank you
