Just wondering lads how do i adjust the ride height of the 180sx?Its fitted with these gab coilovers.Is it just a matter of winding up the two locking collars??Iv already cracked one of the lower collars trying to get them loose and i cannot get the top ones loose even after a can of WD-40!Also do i need to compress the spring as i dont have anyway of doing this so i was trying without?Heres a pic
