I Need A Vacation
Looks in really good condition your really going to enjoy the Si welcome to the forum.
Unfortunately any kind of aftermarket suspension or springs will lower the car. You can look at upgrading your rear sway bar to a 22mm, there are a couple companies that make them for the 9thgen Si. Rear sway bar is probably one of your best bang for the buck handling modifications.I would lower it but I live in a state where you never know how much snow you are going to get so I wouldnt want to get into a situation where I would be stuck if it would snow a lot lol. I was thinking about maybe adding a rear sway bar or maybe changing my suspension but I dont even know where to begin looking. This is coming from a complete noob who never got to working on his car. The one thing I did do was change my shifter bushings to some acuity ones and I'm glad I went ahead with it.
With that being said, any recommendations for rear sway bars or suspensions that can improve my driving experience. Not looking to lower my car.
