Or perhaps the point was obscured by your extraneous code.

Kerning is not determined by plotmath parameters, but by the font  
construction. Install a different font that behaves in the manner you  
desire:

?plotmath
?pdfFonts
?quartzFonts

 > quartzFonts("serif")
$serif
[1] "Times-Roman"      "Times-Bold"       "Times-Italic"     "Times- 
BoldItalic"

 > quartzFonts("sans")
$sans
[1] "Helvetica"             "Helvetica-Bold"        "Helvetica-Oblique"
[4] "Helvetica-BoldOblique"


You do know how to use FontBook.app? It looks like HelveticaNeue- 
LightItalic has tighter kerning than Helvetic-Oblique.

... or edit the one that is on your device:
