I still own my '03 ZHP, and have driven a CS. I agree with equ. Also, when I replaced my ZHP's OEM Potenza RE040 tires with PS2's (CS tires) I lost a bit of the directness I had on the ZHP. The PS2's have rounder shoulders. I find the car is almost better now, since it muffles a bit of the sensitivity of the ZHP. The PS2's are far better tires. More comfortable yet as good if not better performance-wise.
