    Yes it`s PKM but it`s not direct Sachs, PKM also makes their own dampers, but what`s internal in the bodies (if it`s Sachs, PKM own or something else) probably only Hyundai and PKM knows

    They are used in too cold conditions (Sweden) to reduce the amount of cooling air flow, or when cars are not in competition mode (cerimonial starts and so on)

    Thank you. I understand reason due too cold conditions. Using in non competition mode less. Lower power - lower amount of air?

    Engine working on lower load, lower RPMs, etc. so generating less heat, so less cooling needed, and you close radiators to have correct working temperatures
