does it matter wich side you install your torsion bars?

They are pre stressed in the direction of spring rate so the right (passenger) is already twisted a little in its load direction, ccw. Also makes the lca mount up easier . Iirc you have to manually push the lca down a little against the bushing preload for the bars to slide in, or else loosen the bushings and have the lca just hang, bring load onto lca and tighten bushings at ride height.
