SuperPro bushes are tried, tested and proven in Motorsport, which means they deliver outstanding performance. Their innovative design and superior materials offer dramatic improvements in handling and give a more precise feel through the corners. Unlike some polyurethane bushes, with SuperPro products there is no increase in vibration or ride harshness - an attribute that makes them an ideal choice for cars that are used for both normal road driving and track days. All SuperPro bushes come with a 3 Year / 36,000 Mile Guarantee
