i have them mounted on my 07, and i can tell you that 9 degrees is just enuf to notice, but it isnt anything near excessive.
They made an appreciable differnce in bringing the bike alive about 1000 rpm sooner. Im sure if you had the R and D resources, and could machine cams, then you could maybe do better, but i think lennie did pretty good with a part a wrench can change in an evening.

Whoa!!! Nine degrees cam timing is a bunch. I guess that would alter the torque curve some. Although I don't know much about the boxer motors. it's hard for me to believe that Bmw would miss the cam timing by that much, Seems to me they would just put in a different cam. IMHO
