For the ECS drive shaft there are 2 versions:
50mm and 52mm
For the EU Rubber Spec 008 the default setting on the front arm uses a 1.5mm shim and 52mm drive shaft.
Q1: Do the 52mm ECS drive shaft fit well when using 1.0mm to 1.5mm shim?
Q2: Do the 52mm ECS drive shaft fit well when using 0 to 1.0mm shim
Q3: If using the 50mm ECS drive shaft and 1.0mm to 1.5mm shim, does the drive shaft reach far enough into the solid axle drive shaft adapter?
