dont think the k tec springs are apex ones. They are k tec's own ones. no, they are apex ones!
I have just fitted apex 40mm to my car with standard shocks, and if you listen to all the crap about then being "totally shocking and harsh as fook etc etc" then you will be pleasantly surprised! i don't listen, i owned a set for a year and the ride quality and skittling around corners was terrible.
my car sits lovely, handles better than standard so it does handle good! and it isnt half as bad as people make out to be in ride quality. yeah its stiffer but its meant to be! you only notice it on speedbumps and potholes etc so you cant just say dont buy them because of that! eibachs etc will be the same if you hit bumps! eibach are a far superior spring. if you are lowering purely for look, apex are great, they make the car sit perfect. if you want the car to handle like standard (which is very good) and a small drop, sportlines are the way to go.
