Way Motor Works just got the first batch of the new Powerflex complete rear trailing arm bushings. As your MINI gets older these bushing have been wearing out causing the rear toe to change and increase tire wear along with decreasing mid corner performance due to toe change. These new polyurethane bushings replace the entire rubber bushing now. The old version was just a support for the bushing. Powerflex Trailing Arm Bushings for R50 R52 R53 and we have them for the R55 R56 R57 R58 R59 R60 R61 also. We also carry all the other Powerflex Bushings you need for your MINI
