I'm just curious about the 900d. For most road going cars or rally racers 900d is too low to get reasonable steer ratio and lock at the same time ( talked about for several times here ), and for typical circuit racers it's too high. Any specific reason for 900d, instead of anything higher or lower ?
For "Super Fast Race" (13:1) if you use 900d you'll get 35d steering lock, which is too high for typical super racers. "Normal Race" and 900d it'll be 30d lock, which is real. But we still have many street cars to drive and with 900d you'll get no more than 26d lock, or even 20d, which is almost impossible for street cars !
Is there any hardware limitation stopping wheel manufacturers from producing wheels higher than 900d ?
More likely there's hardly anything to gain for manufacturers from offering more lock. I have this feeling the general simming public isn't making much use of 900° or even 720° FWIW.
Even if Logitech had any competitors to speak of (Thrustmaster is content of selling 270° wheels and Fanatec is still too small), there would be little point in starting a 'lock war'.
BTW 900° wheels have been around for some time and only recently we've seen an affordable wheel that is also decently quick (I'm talking about the DFGT). If in the future Logitech releases quicker wheels then they may also start thinking of bumping lock a bit.
All in all I think for the time being 900° is not a bad compromise.
