BGM were so dissatisfied with the quality of all the silent blocks that they took up the issue.
The main focus was on reducing vibrations, and to this end we tested every conceivable combination of silent blocks. Different hardnesses and different hardnesses on the left and right side.
We have now found good hardnesses for the left and right side.
Both the mounting side is with L (for left) and with R (for right), and the mounting position (arrow to 12 h) is embedded in the silent blocks.
