Hey MINI Cooper owners (R52, R55, R57 models), if you're hearing clunks from the back end or the handling feels a bit loose, your rear anti-roll bar bushings might be toast. This VAICO kit is a direct, high-quality replacement to get things tight and quiet again. The kit includes the bushings you need – the inner diameter is 16mm, which is crucial to check against your old part. It directly replaces the OEM part number 33556754823.

Swapping out worn bushings with these fresh ones can make a huge difference in how your MINI corners and feels on the road, reducing body roll and eliminating annoying noises. VAICO is a trusted brand for European car parts, so you know you're getting something reliable. Installation is pretty straightforward for a DIYer with some basic tools and a jack, or any mechanic can knock it out quick.
