To be honest I was told they were the sport lines. They were already on the car. I did put the
eibach pro kit struts/shocks on it in '12. I have no problems with them rubbing other than if there is someone in the back seat and you go over a significant t dip. I'm running 275/40/17 Nittos. The overall ride is stiffer than stock(good and bad). Handling is way better than stock but a little harsh imo. They suck at the Dragstrip. Other than these/stock and the old 70/30's Ive no expierience with spring rates. I am going coilovers with strange adj struts/shocks. Otherwise I'd keep this combo. I liked it for the street and curves.
