The new generation of KYB have the MV float set by limiting the travel of the 20mm shim by using two 12mm x 0.25mm shims. I think you would need to add up the total stack height including the .1mm of the 20mm to make sure you aren't preloading it, then adjust your limiting 12mm travel limiting shims. See photo

Does anyone know if this configuration was also used in the 2020 SEF 300?
