drop spindles

In a nutshell, your ride quality is bad now because your suspension is constantly hitting the bump stops. The stock torsion bars are too soft to sacrifice any ride height, because lowering the ride height also reduces suspension travel. Since the stock bars weren’t really even stiff enough to keep the suspension from bottoming out at the stock ride height, you can’t lower the car with stock torsion bars.

You have two options. Buy the drop spindles. The car will be 2” lower, you’ll still have really soft torsion bars, and you may find that you end up with tire interference or even hard parts on the ground with that amount of suspension travel at the lower ride height. Also, if you don’t lower the car the full 2”, you’ll actually make your suspension geometry worse than stock- add bump steer, reduce camber gain, etc.

Your other option is to buy larger torsion bars. Something in the 1.03” to 1.06” range will allow for a modest drop in ride height, especially if you use a shorter LCA bump stop. Then you can lower the car with the torsion bars, because the stiffer bars need less available suspension travel. A 1.03” bar has almost twice the wheel rate of the stock bars. Plus, when you lower the car with the torsion bars, you improve bump steer and camber gain, which works better with the radial tires you’re probably running because the factory specs were based on bias ply’s. You will also want a good set of shocks to tame the larger torsion bars, but, even a really nice set of shocks and torsion bars will cost about the same as those drop spindles. And your car will actually handle better, not just look cool.
