As I read Lewis' comments regarding braking confidence, I am of the position that he needs to make changes to himself rather than the car, which was designed as a F1 suspension system should optimally be designed which has a primary purpose of keeping the car level at all times so ride height can be as close to static at all times thus allowing for a lower static ride height. Lewis cannot ask that the very nature of the cars' suspension be altered without requesting the system be removed altogether which is not an option. The system appears to be volatile but they are really getting their hands around it, so Lewis can only hope the car will be more predictable than ever going forward.
A major question I have regarding W04 vs RB9 is, with W04 being quicker in qualy trim on so many occasions, how much of that was due to W04s suspension system vs W04s aerodynamic prowess. I suspect W04 did not have near the aero RB9 had as RB9s slim 2014 spec rear wing they were able to run all year proves they had a distinct advantage in this department, but with W04s superior suspension system, were Mercedes able to make up that half second difference in aero performance with a suspension system alone? I believe the gap was possibly that big, but 2014 and W05 will prove this more clearly as the aero field will be far more level meaning we will be able to clearly see just how good the 'Fric' system (or whatever they may call it internally) really is.
If W05 proves its suspension system -which was ironed out with W04- is truly superior to the rest of the field then I believe Merc will have invented the latest version of F1's 'silver bullet'. We, as fans, have been blinded by RB's aerodynamic superiority for so long that we possibly could fathom anyone out-Red Bulling Red Bull, which I believe Mercedes Benz weren't trying to specifically do, hence their potentially genius suspension system which took them so long to produce and perfect, which in turn provides a distinct advantage as other teams will require an equivalent time frame to produce.
Best these holidays,
