[spoiler_dave]

Good day im a newbie here, kakabili ko lang po ng una kong sasakyan yung 1995 nissan lec, ok naman po ang porma at makina at nka lowered n din yung unahan tpos yung likuran stock shock at spring pero parang malambot masyado yung likuran kaya ang problema ko minsan pag medyo maalon or di pantay kalsada masyado malakas yung pag bounce nya kaya minsan hanggang 40-60kph lang takbo ko... pde po ba ko magpalit ng stock height n spring pro mas matigas sa likuran? or baka po meron kyo maisasuggest na mas mgandang paraan para masolusyunan ko ang problema ko... salamat po...

unless you have a lowered car with cut springs, or if you can visibly see you car sagging in the back, then springs will be the least of your worries. car springs (coils) are almost indestructible if the car is driven normally for years and years.

your problem is your shock absorbers (dampers). baka sira na, so the "makaldag" feeling you get is the shock absorber/s not absorbing the shocks properly. change 1 pair at a time (wag isa lang), at isabay mo na yung mga balljoints at stabilizer links, babalik sa dati yan.
