Try to answer two at once, Yeah Chuck, waiting to see if the qtmi people respond to my info request. If any of those Brembos have mounting points like the nissin calipers on our rides, then It's just a matter of taking the plunge and dropping $300 plus moccassins on it. I'll share whatever I find out. Benny, I'll bet honest money that after you install the Progressive Fronts, you'll want the progressive rears. I got my 412's from www.bikebandit.com (bikebandit is the SHIZNITS) for a relatively decent price, and they really help "balance the equation" between the front and the rear. Those really are some of the best mods I've done to my Speedmaster
