linea doesnt suffer a soft suspension at all. the suspension is stiff and very balanced. when u have soft suspensions your car bounces badly on highways too. the real problem is the engine guard is way too low and linea is supposed to have atleast 16" wheels. in europe puntos and lineas at 16 " wheels. ok coming back to the product its called the coil spring adjusters. it just stops springs from compressing. this is very useful for sagging cars like honda civic or honda city where when 3 people sit at back the wheels go in. for record purpose i scrapped my linea 6-7 times when it was new. now i am very much used to it and i never scrap. yes it does scrap in real bad roads, but then the product above wont help in those roads either.
