[QUOTE] If it's the bobbins alone, they are 80 quid a side for a full set. The disc carriers are another 160 quid each on top of that. Harris will do me a complete set of discs with brand new rotors as well for 436 quid. There's not much option really. These ones do have excessive play, so I'm going to pull all the bobbins out and measure the bobbin slots in the rotors and carriers this weekend. Let's see if I can get away with just a set of bobbins for now.[/QUOTE] I'm sure those discs and those carriers are fine Loz, seen very little duty. All the race bikes seem to have quite rattly AP disks but yours did seem to have loosened off a bit since I had it. I originally put slightly heavier shims behind the buttons, deformed them and pressed them down and the discs were nice and tight. They only moved under braking. You could do this again, the vernier will tell all though. I have another set of carriers and disks, the old solid slotted iron type. The disks are slightly warped I think but the carriers are good. You are welcome to all the stuff I have. 'Hog
