the noise only come from 1 coilover, so i thought something is wrong.
performance wise, cant tell, but its quite annoying!!!
though mines squeaks on un even roads as well.
guess that is why its cheaper than NEW!!! ;p
tried to spray wd40? lol, onto the top rubbber mount, but NOPE, noise still there.
probly will try to swap to its original spring,
see if it goes away,
the previous owner reckon the Apexi spring is bit harsh for the road, so he replaced it with a softer springs for the rear.
Its not too bad, noise will go away if window is down. But am chasing for perfections!!!
