Hi. Thanks for the response. I would agree with your initial summary at the start of the thread. There was an improvement but the front brakes aren't as good as I had hoped and are still slightly spongy. I don't believe they need rebuilding, all pots move freely. I just think they are preforming as well as they can with the 5G M/C. Has any body tried changing to a 14mm M/C with the existing front callipers de linked? I admire your determination to stick with the 5G fork lowers and make up new calliper brackets. To be honest here in the UK Firestorm fork lowers are plentiful enough and cheap enough to make it an easier option than fabrication. However you will have something that looks bespoke when you are done. I would still like to know why others members are not using all the VTR parts, callipers, M/C's(front and rear),fork lowers, in preference for Fireblade and CBR 600rr parts they need to be modified, if only slightly, to fit.
