As suggested above to anti-roll bars like there name suggest will control the body roll, will little or no loss in ride quallity.
Quality coilovers will lower, firmer and control the damping better.
Springs alone can be used to control body roll, this is not ideal. You will need much harder springs leading to poor ride quality. Harder springs will also case the standard dampers work too hard. As they are unable to control the deflection of the stronger springs.
Anti-roll bars front and rear work very well. The rear makes a huge difference.
