Well, if you don't care about the profiler and just do the stuff manually - like me - you can set every steering-angle whilst preserving all FF.
It will just look odd when the wheel and hands/arms-animation will not turn further than 720/540/450/270 (depending on the car-model) degrees of rotation. You can disable the animation when driving in cockpit, though.
I personally just stick to the exact same amount of rotation as is animated in LFS. Given that there do exist but few cars like the Mitsubishi EVOs 4x4 Group-N-spec Basic-Rally Cars in the real world-- (which do sport an exact 720° steering-rotation) -- I think it is a fairly reasonable choice to stick to this setting for the tin-top road-cars. It also works pretty well on the less-expensive consumer-wheels like Logitech (G25, DF-GT) which do not provide quite the peak-velocity in simulated FF-caster-steer that real-world "A->B"-roadcars offer with steering-lock about 900-1080 degrees (when equiped with power-steering, at all).
So it really is a matter of "pick you own choice". Just try it out and decide what's best for you, yourself.
Your average happy G25 owner
