Brakes are a SYSTEM -- and if the system is all done well and matches --- from the pedal ratio - to the master cylinder diameter/volume - etc - all of these big brake systems work killer.
One thing some buddies have had to get used to -- COLD braking.... some of these systems have street/track pads in them and the cold braking takes a little getting used to.
Another thing people fail to do -- BED THEM.... and I mean get them smoking hot bedding not just a few random hard braking stops.
