i got it from sunway, and i honestly forgot the shop's name already, cause there's just so many of em. We sourced it from there and installed it at my regular workshop.
I'm selling it because i had a hi/low & hard/soft set that was sent for service, so i got this set and used it for 4 months. My idea is that to buy it first and resell it later because i was desperate for a set of suspension at that time.
