I just got a 13 Si sedan and the first two things I wanted to do was lower the car to decrease the gap and get HIDs. I was wondering which springs should I use to achieve that without changing any other parts. I'm not really into racing and performance like that. I just want to decrease that gap. I'm not trying to be cheap and use inferior products though. I just don't want to waste money and change things that wouldn't need to be changed. I'm looking for 1-1.5" drop. Thanks!
