I don't have the right size line to jump the 2 calipers together. Once I get that Ima try a 6 piston hb w a 4 piston fb. Then Ima change it up and try a 8 piston hb w a 2 piston fb. Just need the line to connect em and see what setup I like.
if I had your set up I would of already linked the brembo to a 4 piston
