Steel spherical bearings will transmit a fair bit of road noise...Do you have working sidepipes ? You probably wont hear it. Nolathane bushes are far firmer than factory rubber and are designed to replace and improve the performance of original rubber.
Steel bushes are good for race cars.( they get rebuilt regularly/weekly ) Nolathane, fitted properly do the job fine..... S**t I should be selling the things ! ;p
