Congrats on a gorgeous Mach 1 !. Just a few things for you to check, looks like missing the extra lower front splitter as well as your front wheel lips. You may want to check if there are still yellow shipping blocks in the front springs as your gap looks a bit large. These are things...
Did your base on the strut on the driver's side twist when you closed the hood? I cannot get mine to stay straight, and some believe this is what's causing it to draw down tighter on that side.
Not "trouble" per se, just difficult to find the bite point in the OEM , the feel is a bit strange. The Steeda spring, to me, let's you feel the engage point easier and shifts are smoother when letting out the clutch. IMO, and many other.
I called Steeda before buying. They advise no issues and have these installed on at least one of their own Mach 1s. Feel free to call and confirm though. Nice folks easy to get hold of
