This mod/upgrade will give your CC01 the much needed flex it needs in the rear. The printed part is the template and the shock tower.
How to use:
Print the part
Place onto the truck.
Mark the shock holes (See picture)
Cutout the yellowed area (See Picture)
Install onto the truck using 8 3mm x 6mm long Tamiya type self tapping screws.
Install the top of your shock using a 9mm spacer and a 3x20mm screw Self Tapping if you have but M3 machine screws will work as well.
Install the bottom of the shock using your usual hardware.
That should be it.
Do some testing and tune the shocks to suit your needs.
I think I used 50 weight oil in mine,
