I only use my DFGT on GT4 and the FFB is quite mild..a little too mild alot of the time. I don't know what GT5P is like but I don't think it would be possible for it to start malfunctioning from the FFB. The overall build quality of the wheel is good as well..not as good as the G25 but good for the price you can get them for. I have heard of problem's with the DFGT pedals but I haven't had any yet. I hope this answer's your question. Cheers, Cougar23
