The OE rubber steering rack mounting bush that secures the rack position is one of those that commonly softens causing vague steering often followed by a pulling feeling on the road, and a less than enjoyable driving experience. PFF85-633  Steering Rack Mounting Bush  is a cheap fit-and-forget solution, improving steering response and bringing back a factory-fresh feel. Fits Polo MK3 up to 2013, fits Ibiza MK4 up to 2015 and will not fit solidly mounted racks.
