Get to know the car before you start modding it...and I don't mean by racing it on the street. You really should come out to the autocross and find out how the car handles stock. THen modify it and go from there. The mods you are talking about don't do anything except make you like all the other people out there with modified imports. Just be responsible and careful. Listen to the recommemdations of these guys here...they know that they are talking about.
