I put the Galfers on my '06 last year.
If i have got this right, later in the production of the K bikes, BMW went to a fixed bobbins and not the separate bobbins that should have come with your bike.
If your rotors came with the bobbins in the rotors, they should be the wrong rotors.
My Galfer rotors did not have the bobbins fixed to them and i used the ones from my original rotors. Everything went together very well except, when i did mine, I found one of the 10 bobbins was a different size than the other 9. I suspect the ass-clowns who replaced the factory rotor with the thicker rotor under the recall from '06 got one of the wrong bobbins.
When I went to BMW to get a replacement bobbin, I discovered that BMW no longer makes/sells the original bobbins. Luckily, I found one at my local wheel shop. Woody's Wheels in Denver.
Anyway, I know BMW offers a "retrofit kit" for the factory fixed bobbin rotors.
Hope this helps.
