So is there more to this story that you didn't tell us? Is there a severe liability issue with BL and extra torque forces that makes BL modified bumpers more susceptible to damage???

Please explain the answer they may have given you a little more. Its funny how people jump to conclusions and don't fully explain the situation.

While I am partial to Calmini and their engineering, I hope that we are truely comparing apples to apples. There is always a very good reason as to why they do what they do. They have been doing this for a very long time.
