The car looks good as it is. You only really need minor things if that depending on your tastes.
Is it your daily? Then you might want to think about coilovers, I mean roads around where I live are crap, and I cannot think mn would have better roads. Especially if you are not going to track it, coilovers really just are not necessary, lowering springs meant to work with the stock shocks are better.
Wheels and tires are always a good first step, just don't go the crazy on the biggest wheels you can afford route so many seem to. Adding 18" boat anchors might look good, but can really hurt the performance of the car. Heck if you are not tracking it I would suggest staying near the stock size, the wheels will be lighter and the tires will be slightly less expensive.
Personally I went with a carbon fiber driveshaft, the lightest flywheel I could find, a new clutch and upgraded fork/bearing. I'm deciding whether I want to spend $2600 on lightweight wheels,
TWS T66f are just so amazingly light. The car looks awesome and no one knows what it is around where I live.
