In a representative set of models, we show that for values of the cosmological spin parameter lambda > 0.03, bar growth (in strength and size) becomes increasingly quenched. Furthermore, slowdown of bar pattern speed weakens substantially with increasing `lambda,' until it ceases completely. The terminal structure of bars is affected as well, including extent and shape of their boxy/peanut bulges.
