Depends on your driving style. If your an agressive driver, you definitely want to get rid of the stockers. If your not, then the stock tires will be fine for you. A lot of people badmouth the RE-92's (myself included), but they are actually a decent all season tires when you don't push the limits.
If you are looking for better tires, there are a few. I've used Dunlop SP5000's and they were awesome. Good wet and dry grip and very predictable when they are about to give.
I've also heard great things about Pirelli P7000's. There are 2 types, just make sure you get the summer ones. I believe they are the P7000 SS's.
Bridgestone also has a set of Potenza's. I can't think of the model number right now, I trhink they are RE-040's or something like that.
Michelin just came out with a new tire, Pilot SPort A/S's. They're supposed to be an all-season tire that performs like a summer tire. But, they are extremely expensive. ABout $200/tire.
These are just a few. You should check the TireRack and read some of the reviews that people write. That'll give you more of an idea of which ones to get.
