i just installed the eibach sportlines on my celica. the ride is a lil stiffer than the already stiff stock ride. i love how low it sits, but hate having to go into gas stations at an angle. speed bumps can be a hazard too, or atleast here because the roads are crappy here in new england. if you get the sportlines i strongly recommend a rear alignment kit because of how the back tires sit with the drop.
