Since it's allways the back of the X6 chassis that gets worn-out the worst (for me anyway).
I made this: An embedded rear skid / wear plate. So it can be replaced if it gets worn
Needed:
- Random scrap piece of Aluminium / Stainless steel (~ 1 / 1,5mm thick)
- (Acces to) a mill / cutter
- 5 minutes of spare time.
( I know the pictures are not anywhere near of "Jimmy would approve" quality

, but you get the idea......)
