let me introduce my ride 1st
type is TIMOR S515 MY 1997. in korea known as KIA. (i guest)
the platform and the body is similar with KIA Sephia.
with MY 1997 so it's about 13 year old
i'm facing problem with the shock breaker. the oil it's leak on the front shock.
so that's why i have a plan to replace it with the new one. i need suggestion on which shock breaker should i choose. since the original parts is N/A. soft shock is preferable. please advise...
