hmm the topic has been covered alot but yea sportlines are indeed a good purchase i mean heck it was my first mod I did on my car, appearance is perfect not too low but just enough for you to notice the difference unlike the prokit. handling wise? its really smooth and well planted when you drive around a roundabout. One thing to mention though for the people who are planning to get sportlines they are lower then stock and prokit so you may want to upgrade shocks in the near future such as pro shocks by eibach when they are combo'd up they are very good, I learnt that koni fsd's are more like stock dampers to go with stock springs or prokit springs so its pointless to combine koni's and sportline together.
oh yes forgot to say..for people who are worried about poor roads, speed bumps and dreaded indoor parking (ncps) you won't have a
problem with sportlines i not experienced any issues. and soon to upgraded to newer shocks soon.
I hope this information helps.
FR choices
good upgrades? KONI FSD's + PROKIT EIBACH SPRINGS / KW Coilovers... / and Eibach sportlines
also good idea to have your car tracked when springs changed just to be on the safe side too.
