door rams so the doors dont slam

[V8Dom]

hi
has anyone worked out which door rams are more suited yo the Ultima doors as im sick of passengers slamming the door when they shut it

All the other cars ive been in recently Enzo , lambo, maclaren and even Rdical you have to pull the door down rather than pull and oh!!!!! it just slams shut as the door is too heavy for the ram>

any ideas please?

i wonder how we measure pressure needed?
I will email Richard
