So it's time to replace the S3's front drop links and anti-roll bar bushes. I have changed the rear drop links and noticed the bushes on the rear are looking skabby. The front ones appear to have a plastic collar that has broke off the brushes. Can I remove them and replace them with polybushes without the plastic collars. Anyone know what size bushes are needed for the front and rear? Is it easy to change them? The rears don't look to bad if I drop the rear box.
