Yes the car runs great with RS pistons, very smooth and strong. When my wrench disssembled my engine the original CIS pistons were in good shape. However I wanted everything new. I decided on RS pistons for a few reasons - They were forged not cast like CIS (stronger piston), future option to use webers, Price new was the same as CIS.

Overall I feel the car runs better with the RS pistons.
