Bro, wanna ask you, for my wira everytime will kena botom when crossing bump. and when the car got 4-5 ppl inside, even corner also will kena tyre. ppl told me wira is like this. But how to fix it? Is the Spring problem or the absorber? Some ask me to change the spring to waja spring, some ask me add 3inch rubber to the absorber. which is correct?
