First of all your springs will be just fine because your car is daily driver car...second you want sway bars not strut tower bars....either go to RMDSM.com or Stillen.com for those....because sway bars reduce roll in the car and let you corner better.....Strut Tower bars will help get rid of suspension vibration the most......also with our type of car go nothing bigger then a 17inch rim....if you want even more imput just ask and I can keep going
