Just wondering if anyone is using the BDX lightweight track shaft drivers on the M Series. Looks like a nice reduction in rotating mass but wanted to know if you can actually tell a difference between stock and the aftermarket drivers.
Yup, put them on my M7 for one ride last spring, along with the light-weight rotor, 10.4" secondary, and seemed to make it quite a bit more snappy off the bottom, would recommend.
i have just the drive shaft in my m7, lots nicer than the stock one, the short little bolt makes me feel alot better than the long one with the spacers on it that goes all the way through on the stock one
