When using JVD-RC Clutch Shoes, make sure the clutch bell is 100% free from former debris.
Use a dremel and grind the inside of the clutch bell. Even with a new clutch bell dremel the inside.
The smoother the inside of the bell the longer life U get out of a set of shoes.
When after some driving the shoes look kind of dark or even black it is a good sign. They will look shining after a few tanks.
