You can stiffen up the springs, but your car and I mean ANY car should go to the bump stops without the tires hitting anything. Otherwise it’s always going to be something, no passengers in the back, half a tank of gas, etc. get the right size and offset of wheels and tires, flare the fenders, mini tub it or do what you have to do to allow full suspension range first. Now that I’ve blabbed about that, I use 5 leaf mid eyes and GR2 shocks and it rides good plus is stiff enough for casual driving.
