well...umm...i think i'm gonna speak for most people when i say that we'll have some questions to ask you before we answer yours...

is it stock right now? what do you want to do with it? how do you want it to behave? is it your daily driver? how much money are you willing to spend?

but MOST IMPORTANTLY...if you're thinking of doing something specific to your car, use the oh-so-amazing SEARCH feature and read up on existing articles so you don't post a question to which there is already an answer.
