71 plate MG5 LR Exclusive - Static roof bar rating?

[thedomg]

I'm well aware of the 75kg dynamic load limit for the 71 plate MG5 LR Exclusive; can anyone point to a reliable source for what the static load limit is?

Interested because of possible roof tent use - if there was one under 75kg, that'd be ok for dynamic load, but I don't really want to trash the car when I lug myself up there!

The rule of thumb seems to be that the static load is 3 to 5 times the dynamic load (according to roof tent manufacturers)
