You have no clue who makes them. I doubt all urethane bushings are the same. I have Ireland Engineering urethane bushings. Some people feel the car is more planted. I think it's more twitchy when I go over a bump. Maybe it's the urethane rear trailing arm bushings I also have. A local, highly regarded, performance shop told me to stick with rubber. I should have listened to them. YMMV. Are your subframe bushings shot? __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org |
