the problem i can see with hardrace ones is that if you dont clock them properly, they will tear and destroy the mount

obviously i want to lower my car a fair bit so thats why i looked into spherical bearing types... but they are not economical for a daily as they can wear out the bearing itself

next best was the nolathane because you dont need to clock them as they move within the bush
and they have a circlip to hold them in place also
