Don't bother buying anymore performance mods until you know your getting a custom tune and have decided to track it more whatever your track style is 1/4 mile, Oval, Road Course or AutoX. Do yourself a favor and get your wheel and tire decision made first this is the #1 upgrade in car handling you can do easily especially coming off the stiff not so grippy runflats.

To elaborate on StM's post... I'll leave the bolt-on discussion alone but i'll bite on the tune conversation. If you have readily available pump E85 go with Vermont Tuning otherwise do yourself a favor and try and find a dyno shop locally you like and maybe trust enough to tune your car. The companies e-mailing tune files back and forth are hacks and jokes some admittedly tune over-cautious and give crap results others overtune and blow-up engines. Some are just plain not that great I think of all the one's StM listed Vermont is the only solidly upstanding one.

Also a note when you go to get a dyno or any tune wether you go e-mail or not you will need to uninstall the RaceChip hardware entirely.
