In my experience (from both schumacher and previous cars) the trick with suspension arm stiffness is to get the right balance between too soft (and losing responsiveness) and too hard (losing traction). Striking the right compromise will gain time, without affecting car handling balance. 99% of the time cut arms are the best compromise for the Mi5 & 5e.

Very rarely I would run un-cut rears, but always cut fronts.
