correct me if I'm wrong.
the 8mm mod increases the camber when rear shock is compressed. and decreases the camber when rear shock is stretched. （imagine a mild version of Macpherson independent suspension）
With the high CoG this truck has (thanks to the belt system w/ high gearbox), the truck rotates a lot when cornering.
During corner, having more rear camber when the car rotates, give both the rear tires more contact area with the ground.
leading the truck to have more rear grip, which it lacks.
Personally I just use the inside hole on the rear upright, increase the distance between the linkage point and the lower pin on the upright.
And use the inside hole in for the rear ball stud. decrease the distance between the linkage point and the suspension mount pin.
This produces similar but less effect as 8mm mod does, works well.
*I used the exotek locked clutch and loosen the clutch to give the rear less power. Since 4wd SC with 550 4pole motor is quite overpowered (at low speed), this setup is working just as nice as center clutch does.
