Finally had our first auto-x this weekend and the tires did great! I cant say they are better than the RS-3 but certainly no worse. My car is stock except for APR sway bars front and rear set to the softest setting on both. I ran them at 45 psi rear and 50 psi front cold. It was 87 deg partly sunny. After each run the fronts showed a spread of around 10 degrees across the tread and the rears around 5. It seems as if they roll over a little less than the RS-3 did. Try them out you probably will like them.
