    Nice one

    Yes well spotted on the GSXR750 Brembos.

    I almost bought new monoblocs then a cheap set popped up on ebay in Italy so I jumped on them.

    My only concerns are:
    - Fitment might be a bit close for my 16" wheel. As you cahn see my mounts don't keep the calipers as close to the forks as the speed merch jobs do.
    - I'll like the improved braking performance on my 2010 so much I'll want to do the upgrade on my 2014 (and not sure what complexities are added because of ABS)

    I'm all for bling when its functional.

    Big Steve, 
                  Your swish brackets are for the 11 1/2" discs, or did you opt for the 13" disc variety? 13's might be tight on the 16". My glitter guts wheels are 18", plenty of room.
    The improvement in braking is really in feel. Not as mushy as the originals.
    Stopping power similar to original without reefing on the lever as hard.
    ABS is catered for by Goodridge lines. Not as fancy as the Venhill fittings. Phone John Stanmas in QLD 07 5447 741. Yeah, that's a plug.

    Correct I have mounts for 11.5s (It'll be close but i'm confident/hopefull) If not then I'll just have to go 18" Rim.

    The hesitance for doing the 14 as well is that it has all magnum shielding brake lines/splitter box etc. 
    Aren't the stock Rotors 11.8" on the Fatbob's ?
    Looking at the radial mounting blocks, Fatslim's mount puts the caliper much closer to the wheel center than your's Big Steve ?
    Just by eye, if Fatslim is using an 11.8" rotor,  it doesn't look like the diameter will be big enough ?

    Interesting observation speedzter....
    I have the Stinger disc rotors, pretty certain they are 11.5" ( or 292mm for us regular folk )

    Big Steve, question here, have you fitted up a wheel with discs to the bike?

    Pretty sure all Dyna's since about 2006 went to 11.8" rotors (front - rear is still 11.5").

    You're correct speedzter, I stand corrected. 
    Hard to measure accurately when they're on the bike, but yes, they appear to be 11.8" or 300mm. 

    Back to comparing Big Steves brackets....
    There's 80mm between the top mount surface and the centre line of the lower fork slider fixing hole.
    Big Steve, what's your measurement? 

    On mine, the pad surface area sweep safety margin on the outer rim of the disc is minimal, visible, but minimal.
    Could we PM each other to further this subject?
