Description Reviews Powerflex Bump Stop Kit for any MINI you have! This a universal kit with bump stop and coverings. May require some trimming to make things fit better. Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension for better handling, more driver feedback, and better tire wear. Powerflex uses premium polyurethane materials for minimal NVH (noise, vibration, harshness) and increased longevity over the stock rubber bushings. Bushings come in pre-determined durometers (measured hardness) from Powerflex to work best in each particular location. The street bushing will work best for mostly everyone. They have been spec'd by Powerflex to be the best durometers for your application and are 70A (Yellow), 80A (Purple), and 95A (Black). Powerflex grease is supplied with every dynamic product. We suggest using only this grease for lubrication. Due to grooves and knurls cast into the material to hold the lubricant, bushings will rarely need re-lubing. We do not suggest using an "anti-seize" product for lubrication. Warranty: All Powerflex bushings are made in the UK and come with a 1 year, unlimited mile warranty. Instructions Download
