I have about 3000 miles on the clock with my 2015 GT and have on occasion noticed when making a 90 degree left turn that the sterring almost feels like it has a "dead spot" in it. When the steering wheel is turned to around 90 to 120 degrees to the left it is like the self centering you normally expect from the suspension caster is absent for a second and rather feels more like it wants to pull more left rather than right. I have to give the wheel some input before the self centering effect seems to return.

I should mention the alignment of the car seems perfect, it tracks dead straight at low and high speeds and the steering otherwise feels fine. I havent hit anything and there are no odd noises or other complaints. I am wondering if this style of suspension geometry could have this "dead spot" feeling inherently or if it is related to something else like the 20" factory wheels and wide rubber. I have tried the various steering modes and the "problem" if it is one seems present in all of them. It doesnt happen on all left turns but it happens enough to notice so I suppose it could also be attributeable to road surface and how it interacts with the tires and suspension.

I come from driving a 2012 Infiniti G37 that I believe had a double wishbone type of setup so I am curious if this is just a characteristic of the double ball joint suspension in the Mustang or related to the larger wheels/tires.
