Ok you probably do want to lower it. First of all make sure you dont get to a rim too wide because it will rub the fenders when u turn all the way. I think 18's would fit with a 2" drop. Some people say that springs gives a better ride but i personally think coilovers are better. The only thing is u have to know what u are doing with those adjustable coilovers to make sure ur hight is not out of wack all the way around. As far as brands i would go with Tein or Koni's. Remember u get what u pay for. Teins are a little on the expensive side but i think it is worth it. Also dont forget to install a camber kit if u lower to keep the tires from wearing badly. Well i hope this helped u.
