what weather conditions do you have? summer ultra high performance tires would be the best type if it doesn't snow much or rain too much.. the best wet dry traction tires would be michelin pilot sport ps2's. acording to a side by side tire comparison in super street mag. now if your into cornering dry slalom on in that same article the best was bf goodrich g force T/A KD, but they did not so great in wet conditions, best wet slalom was goodyear eagle F1 gs d3. I've got falken ziex 512 all season tires because I get a lot of snow and rain here, they grip pretty good for all seasons though I think. also for cornering if you got yourself a set of lightweight 17's and put profiler tires with a 45 or 40 series tire on it, it'll give you a stiffer sidewall and better cornering ability. a lot of people roll with yokohama parada's and toyo proxies, but they're not nearly as good as the michelins, but it's what a lot of tire places will suggest you get, especially since the car comes with yoko's on it.
