Shouldn't be a problem if you don't also load the car to the gills at the same time. Max rated capacity is pretty high -- seven adults plus 200K of luggage....

Brakes are heavier front and rear, etc. Lower rear ratio, starts in second unless you floor it.

SLS will hold it level until or unless you exceed the capacity of the accumulators.
