i recently change all my shock absorbers as my car just over 3 years, 50km. bought kyb absorbers from yuen thong for abt $420, 2 x front and 2 x back.
change them at autosaver for 150 with normal alignment. during the change, was informed that they will change my mounting bracket if necessary and each piece cost $45 - luckily no replacement required.
total damage $570 but honestly my car still feel about the same haha..
