Don't let folks tell you an unrealistic wheel is any good, it's simply not true.
Each to their own preferences. A wheel with less than 900 degrees is something I'd rather call a toy than a simulator hardware. Concerning pedals, I suppose you haven't tried a G25/G27? I don't think the pedals would take damage even if you ran them over with a bulldozer.
Good thing you got your settings sorted, though from what I can tell, they are heavily going against the natural force feedback that LFS throws at you from the front wheels. Centering spring effect should never be needed with any proper steering wheels in LFS.
