Just 1 question I'd like to get the answer to sooner, did you replace the brake booster or not?
The first two pages in this thread answered your question about the booster difference between CCB and iron rotors in the M3/4 -no need to change the brake booster if the 6/4 calipers and iron rotors are retrofitted to the M3/4.
Thanks for including an answer.

In my defense, there was a fair amount of conflicting information on those earlier post. CCB booster more powerful, no iron booster more powerful, no there's a servo shared with x, y, & z (v doesn't share) that can be adjusted. Friction this, friction that, it was because of weight or blah blah. Seemed to end without a consensus on this topic.

If someone with the iron rotors doesn't need to change the booster then does someone with ccb need to replace the booster if they went to the iron rotors? Or is this a coding issue?

Anyway, not having to replace the booster makes this a very attractive alternative over the ccb retrofit for me!
