Spring pad front, 3 nubs, 18 mm
The vehicle level is determined both by the condition and selection of the springs and by the thickness of the spring pads.
If you want a large ground clearance, use the thickest spring pad, for "lowering" use the thinnest spring pad.
For info:
1 nub = 8 mm
2 nubs = 13 mm
3 nubs = 18 mm
4 nubs= 23 mm
