Gotta go with the Sportlines. Check out how my baby sits on them with 18's.





She's got a PERFECT stance now, and the drive is so much better and stiffer.

 

^^^ it looks like your rubber is slightly too big man, I don't have pics right now but I have B&G's on my ion (not the same but similar) handling is stiff, ride quality is great, and the stance is how the car SHOULD've came from stock ( i feel) not to low not to high, they dropped the car about 1.5-2 inches front and back, it's close to rubbing things but just enough not to

 

unless you plan on getting the koni struts/shocks, STAY AWAY FROM THE RACE SPRINGS! spring rate is too high for any stock struts/shocks.

but the other thing to consider is everyday drivabililty. i like having a stiff suspension, but i drive alot and my car is my daily driver so i cant go linear or high spring rate. so i went with progress and love it. i have driven from ohio, through kentucky (down i-65, so people who know that know its horrid!!!!) and tennessee. then headed east and then south to florida. the ride was great, but regret some of those holes i hit on the interstate at 75mph which were unavoidable seeing that they cover the entire road!!! the drop is just about where i want it. i like it where i can barely get my fingers between the tires and wheel well.
