I have kings station wagon rear springs in my sedan, its lowered and tows a car trailer really well. The trailer I tow with a Commodore on its back weighs about 2200kg all up
The wagon springs are slightly heaver in the spring rate and seem to cope with the ball weight over 200kgs very well.
An added benefit is the heaver spring rate tends to stop the massive under steer these cars have when pushed with std springs. The ride quality is not really effected
