I have all the stuff to do the BBP front disc conversion. Should I buy the Eberg small wheel cylinders to run with the 3"ers? What does it take to swap to the 11.75 on the front?

The 11x3 aren't neccessary and just weigh things down. Just get a the right pin or slider caliper adapter to get to 11.75 disks
