Is there a way to improve kerning on mathematics?

Question

It seems that some mathematical formulae do not have as good kerning as standard text? Taking a specific example, I would like to change

enter image description here

The version on the left is LaTeX produced from \left(\frac{2\pi}{T}\right)^{\frac{8}{3}}, whereas the version on the right is a mock-up created in MS Paint.

For individual cases you can add some \! before the fraction. — percusse, Sep 06 '12 at 11:35

The usual negative space commands such as \! (See Large negative spaces )from the math-mode can be put before the exponent to shift it to the left.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
\left(\frac{2\pi}{T}\right)^{\frac{8}{3}}
\]
\[
\left(\frac{2\pi}{T}\right)^{\!\frac{8}{3}}
\]
\[
\left(\frac{2\pi}{T}\right)^{\!\!\frac{8}{3}}
\]

\end{document}
