A year ago here at BF we had revealed that BMW M was working on CF suspension components. More specifically they were to be used in the M3 and M4 as the goal for the M engineers was to get the power to weight ratio of the F80 generation better than that of the E90 CRT. To do that they were exploring every option they had to shave weight, much like a hardcore mountain biker using titanium bolts the guys and gals at M were focussed on the scale.
