Socket head screw M4x40 or M4x45 -> shorten the hexagon socket screw
Front spring -> 0.8x12x40 mm -> is also working for the rear -> more spacers needed
Rear spring -> 1.0x12x40 mm
I used three spacers for the rear and one for the front.
To make the suspension run more smoothly, an O-ring 4.5x2mm can be inserted in the shaft around the screw.
