How should I customize my Civic?

I own a 2007 honda civic sedan. Any suggestions for customizing or tuning it?

customizing, well... that's up to you. but in the tuning department i might giv you a tip. i own a customized Civic and i have learned that the civic likes a superchrger more than a turbo. yes, the turbo might give you a bit more grunt at higher revs but fit a hefty centrigufal s.chrger and you get a livley motor that loves to rev. the Civic engine is absolutley perfect for a s.cherger and it dosn't "mind" streching to a limit. another option which i might offer is actually fitting a twin chrger (if you really want to built a rocket), meaning fit a small s.charger for the lower rev band in order to get you that low end grunt, and a small/big turbo for that high-end kick. this would make your car absolutly unbeatable. with these kind of mods though, make sure that u have a strong and well working intercooler.
and i always reccomend on what i call the "magic 5": s.charger/turbo, firmer suspension, bigger and more powerfull brakes, stickyer tyres and a nice exhust - i love HKS exhusts, in my opinion the have the best muffling sounds and they make any car sound like a angry V8 - good luck!
