Shocks won’t lower the car, unless for some reason you have air shocks installed and pumped up in the front.
Changing the ride height with the torsion bar adjusters is the easiest way to do it, but, there’s more to it. If you lower the car with the torsion bar adjusters, you lose suspension travel in compression. So, if you lower the car very much, you’ll end up bottoming out on the bump stops when driving the car. The way to compensate for the lost suspension travel is to use larger (stiffer) torsion bars. That reduces the amount of travel needed.
If you lower the car a lot, you not only have to replace the torsion bars, but the factory lower bump stops as well. Shorter lower bump stops allow for more travel. But you have to match your suspension rate with the amount of travel you have remaining so you’re not hitting the bump stops all the time.
And any time you make changes to the ride height using the torsion bar adjusters you need to have an alignment.
