Actually, both can make a nice difference. I put on the beefier sway bar first, and then shock adjusters many months later. BOTH made a significant difference in the ride for me. Also, the larger you are, or the more weight you carry, the more you need both.
This is the entire key to the lock. The machine is designed for the average rider weight. If you are not average size, either lighter or heavier it makes a difference.
The reality check is how good do you want the machine to be and / or handle? Springs support the weight, the dampers control. Springs come in all sorts of sizes and rates. As for preload, the adjustment to set the springs to control ride height, some shocks have them others do not.
Magic happens when the springs are well matched to the chassis and the rider.
When a spring is preloaded it can alter the ride height, it will never changes the springs rate. It will move the initial force and final bottoming force, but never change the rate.
In general terms, it is best to run the least preload and firmest spring, within reason to obtain the best handling and bump compliance. Soft springs that are over preloaded will often ride harsh and not control the vehicle well. It will be better than too little preload, but is certainly not optimum.
In regards to the front Elkas, these are simply a more advanced shock. Elka also may have decided upon different spring rates. Honestly I don't know. It is very nice to have clickers if you use them. The simple rebound clicker can stabilize the chassis a lot.
As for the swaybar, it too is a spring. As a spring it does not hold the bike up like the coilsprings. The swaybar serves as a link to control chassis roll. The firmer the bar, the flatter the chassis will corner.
So, in simple terms, the chassis and handling can be made to corner flatter with either firmer springs, more preload or a firmer swaybar.
You as the owner need to decide how far from the mythical average rider you are. In the end, the best target is to maintain the original ride height with this mythical rider, be it by adding preload or changing springs. If you riding style prefers a flatter cornering vehicle, opt in for the swaybar.
All the best in your choice.
