torsion bars / drag racing
Yes but on a hard launch. I don't want my front end loading and unloading several times down the track like an old buck board. Hench a good set of shocks, and I'd say the lighter the spring the more the importance of controlling said bounce. For most racers double adjustable is an expense you can spend elsewhere. Your either in to them for the wow factor or trying to fix some other point in your suspension that is lacking. In fact, I'm personally of the opinion I want to minimize the rise and fall, not create more. I want an arrow, flat and wicked fast with minimal porpoising.
