If you do weight reduction then I would suggest a lowering kit, otherwise I would leave it be since it is going to cost a bunch more than what you would get back in results.

When I do my mods they are either free or cheap. Weight reduction-free, programming the ECU-free, corrugated plastic undertray and grille blocke-$10 but raised fuel economy about 5MPG so it is worth it since I drive my car soo much. I have put 11K miles on it since March so I have saved probably 40 gallons of fuel with that mod. So it paid for itself about 9 fold.
