I am pretty sure that you cannot that with the native TSpinEdit. It seems that no one is happy with it, so there are plenty of spinedits in third-party components.

As said above, not in a TSpinEdit, since the OS/WidgetSet controls what is displayed there.
Alternatively you can use a TMaskEdit with a proper EditMask (from the top of my head: '99;0;0').
The las 0 in the mask (after the second semicolon) makes all blanks shown as '0'.
Then instead of converting Text to an integer value, use EditText instead (with '00' in the control Tex will an empty string IIRC, whereas EditText wil be '00').
You could also make a control that inherits from TCustomSpinEditEx (LazControls package) and override the method that draws the text in the control to zero-pad with as much zero's as needed.
(You may want to introduce a property that controls the amout of zero-padding.)

Probably all non-native SpinEdits have the same drawback- they look odd, because they are not using a real spin edit, but a text box + an updown control
Examples:

Well, they don't use a "real" spinedit, because of the restrictions the WS imposes upon us.
See the numerous issues about spinedits in the bugtracker.
You might be able to hide the up-down widget and let the user use the up-/down-button or the mouse-wheel (AFAIK this (keys/mouse-wheel) works out of the box for tspinedit(ex)).
