I'm going to buy some stiffer rear springs for my 244 because it's sagging bad. I have two options, one is the standard wagon rear springs or i can get one that is even stiffer, wich is intended for wagons that carry a constant heavy load, it's suppose to be 30% stiffer than the wagon spring. What do you recommend? I will not carry a constant heavy load, but will carry a somewhat heavy load of people and mountain gear on occasion. Since the wagons also a prone for sagging i'm thinking of the stiffer spring, but i don't want the car to be higher at the back than front.
