The lower and higher you go the harsher the ride. Low will hit the bump stops over bumps and too high takes all the spring out of the front end. It will ride like a old wagon.
The bump stops are the only thing you have to worry about. Well, and getting the right alignment numbers.
Nothing changes with spring rate by adjusting the torsion bar bolts. The car weighs the same, there is no “twist” added to the bars, the adjusting lever just sits at a different angle to the torsion bar hex.
