Hmmmm...after getting my car, the first big mod was lowering it.

Then my friend gave me a free intake, and a free strut bar. All within the first 10 days of having it.

But if you're starting from scratch, dont rush anything. I speak on the behalf of many others when i say this, "do it right the first time".

Go for the suspension mods first. (dont lower without getting good shocks, dont follow my example) FYI, suspension pieces for a coupe or a sedan are the same.

One mod i highly recommend is a good short shifter and bushings. I waited almost 2 years to get mine, and i regret it badly, i wish i got it like within the first month of ownership. Its relatively inexpensive and changes the feel for driving dramatically.

Wow, i sound like a FOB. o well hope i helped
